Answer 12

None of the tables shows a proportional relationship because for proportional relationships, as x increases, y increases or decreases at a constant rate.

Answer 13

but i cant answer none cuz it doesn't have it

Answer 14

In that case, you can choose the option that most closely resembles a proportional relationship. In that case, option A comes closest to a proportional relationship. While the values of y aren't directly proportional to the values of x, the ratios between the corresponding values of y and x are relatively constant (approx. 11, 7.6, 7.25, and 6.8), which is a characteristic of proportional relationships.

Answer 15

so it is
X 1 3 4 6
________
Y 11 23 29 41

Answer 16

Yes, that would be the closest option to a proportional relationship.

Answer 25

Ruth bought a piece of farm machinery valued at $50,000. Over a period of 10 years, the machinery lost value at a constant rate. The graph below models this loss of value.

A coordinate graph is shown.

The graph is titled 'Loss of Value' and has an x axis labeled 'Number of Years' with coordinates labeled from 0 to 10. The y axis is labeled 'Value in Dollars' and is marked from 0 to 50000 in multiples of 10000. A red ray on the graph begins at 0 comma 50000 and extends down and to the right through the point 9 comma 10000.
Which statement most closely matches this relationship?

Answer 26

The statement that most closely matches this relationship is: "The machinery lost a total value of $40,000 over 10 years at a constant rate of $4,000 per year."

Answer 27

Laura is designing a rectangular porch for her house. On her scale drawing, the vertices of the rectangle are (2, 7), (8, 7), and (2, 9). What are the coordinates of the fourth vertex?
A. (8, 9)
B. (7, 9)
C. (7, 2)
D. (2, 8)

Answer 28

Since the porch is a rectangle, the opposite sides of the rectangle should have the same length. From the given vertices, we can see that the distance between (2, 9) and (2, 7) is 2 units, which means that the length of the rectangle is 2 units. Similarly, the distance between (2, 7) and (8, 7) is 6 units, which means that the width of the rectangle is 6 units.

To find the coordinates of the fourth vertex, we can add the length and width to the coordinates of the bottom-left vertex (2, 7). So, the coordinates of the fourth vertex would be (2 + 2, 7 + 6) = (4, 13). However, since this point is not one of the given answer choices, we need to check our work.

We can use the distance formula to check if the sides of the rectangle are equal in length. The distance between (2, 7) and (8, 7) is √(8-2)² + (7-7)² = 6 units. The distance between (2, 7) and (2, 9) is √(2-2)² + (9-7)² = 2 units. The distance between (8, 7) and (4, 13) is √(8-4)² + (7-13)² = √32 = 4√2 units. The distance between (2, 9) and (4, 13) is √(4-2)² + (13-9)² = √20 = 2√5 units.

Since the opposite sides of the rectangle have the same length, the correct answer choice is (D) (2, 8).

Answer 29

Use integer values of x from –3 to 3 to graph the equation y = |–x|.
A. graph A
B. graph B
C. graph C
D. graph D

Answer 30

To graph the equation y = |–x| for integer values of x from –3 to 3, we can substitute the values of x and find the corresponding values of y. Then, we can plot the points (x, y) on a graph and connect them.

When we substitute the values of x from -3 to 3, the corresponding values of y are:

x = -3, y = |-(-3)| = 3
x = -2, y = |-(-2)| = 2
x = -1, y = |-(-1)| = 1
x = 0, y = |-(0)| = 0
x = 1, y = |-(1)| = 1
x = 2, y = |-(2)| = 2
x = 3, y = |-(3)| = 3

So, we get the following points: (-3, 3), (-2, 2), (-1, 1), (0, 0), (1, 1), (2, 2), (3, 3).

We can now plot these points on a graph and connect them to get the graph of the equation y = |–x|.

Out of the given answer choices, the one that matches the graph is (C).

Here's the graph of the equation y = |–x| for reference:

Answer 31

The ordered pairs (2, –21) and (5, –45) are solutions to which of the following equations?
A. y = –8x – 5
B. y = –8x + 5
C. y = 8x – 5
D. y = 8x+ 5

Answer 32

We can use the given ordered pairs to determine the equation that they satisfy. Let's start with the point (2, -21):

y = mx + b, where m is the slope and b is the y-intercept.

-21 = 2m + b

Next, we'll use the second point (5, -45):

-45 = 5m + b

Now we have two equations with two unknowns (m and b). We can solve for m and b by subtracting the first equation from the second equation (to eliminate b):

-45 = 5m + b
-(-21 = 2m + b)
--------------------
-24 = 3m

So, m = -8. Substituting this into the first equation and solving for b:

-21 = 2(-8) + b
b = 5

Therefore, the equation that satisfies both given ordered pairs is y = -8x + 5.

The correct answer is (B).

Answer 33

Which is a rule that describes the translation of a point from (–5, 4) to (–1, 2)?
A. (x, y) arrow(x – 4, y – 2)
B. (x, y) arrow(x + 4, y – 2)
C. (x, y) arrow(x + 4, y + 2)
D. (x, y) arrow(x – 4, y + 2)

Answer 34

To translate a point in a particular direction, we add or subtract the same value from both the x and y coordinates of the given point.

In this case, the point (-5, 4) is being translated 4 units to the right and 2 units down to get to the point (-1, 2).

So, we need to add 4 to the x coordinate and subtract 2 from the y coordinate of the original point (-5, 4). Therefore, the rule that describes this translation is:

(x, y) arrow (x + 4, y - 2)

The correct answer is (B).

Answer 35

ΔPQR has vertices P(5, –1), Q(0, 8), and R(7, 5). It is translated right 3 units and up 6 units. Find the coordinates of P', Q', and R'.
A. P'(8, 5), Q'(3, 14), R'(10, 11)
B. P'(2, 5), Q'(–3, 14), R'(4, 11)
C. P'(8, –7), Q'(3, 2), R'(10, –1)
D. P'(2, –7), Q'(–3, 2), R'(4, –1)

Answer 36

To translate ΔPQR right 3 units and up 6 units, we need to add 3 to the x-coordinates and add 6 to the y-coordinates of each vertex.

The original vertices are:
P(5, –1)
Q(0, 8)
R(7, 5)

Adding 3 to the x-coordinates and 6 to the y-coordinates, we get:
P'(8, 5)
Q'(3, 14)
R'(10, 11)

So, the translated vertices are:
P'(8, 5)
Q'(3, 14)
R'(10, 11)

The correct answer is (A).

Answer 37

The point Q left parenthesis 9 comma negative 1 right parenthesis is reflected across the y-axis. Use arrow notation to describe the original point and its reflection.
A. Q left parenthesis 9 comma negative 1 right parenthesis right-arrow Q prime left parenthesis 9 comma 1 right parenthesis
B. Q left parenthesis 9 comma negative 1 right parenthesis right-arrow Q prime left parenthesis negative 9 comma 1 right parenthesis
C. Q left parenthesis 9 comma negative 1 right parenthesis right-arrow Q prime left parenthesis negative 9 comma negative 1 right parenthesis
D. Q left parenthesis 9 comma negative 1 right parenthesis right-arrow Q prime left parenthesis 9 comma negative 1 right parenthesis

Answer 38

To reflect a point across the y-axis, we negate the x-coordinate and keep the y-coordinate the same.

In this case, the point Q(9, -1) is reflected across the y-axis, so its x-coordinate will be negated but its y-coordinate will remain the same. Therefore, the reflection of Q will be at the point Q'(-9, -1).

Using the arrow notation, we can describe the transformation as:

Q (9, -1) -> Q' (-9, -1)

The correct answer is (B).

Therefore, the answer is: Q (9, -1) → Q'(-9, -1).

Answer 39

Ruth bought a piece of farm machinery valued at $50,000. Over a period of 10 years, the machinery lost value at a constant rate. The graph below models this loss of value.

A coordinate graph is shown.

The graph is titled 'Loss of Value' and has an x axis labeled 'Number of Years' with coordinates labeled from 0 to 10. The y axis is labeled 'Value in Dollars' and is marked from 0 to 50000 in multiples of 10000. A red ray on the graph begins at 0 comma 50000 and extends down and to the right through the point 9 comma 10000.
Which statement most closely matches this relationship?

A. The machinery ages 3 years for every $10,000 loss in value.
B. The machinery ages 5 years for every $10,000 loss in value.
C. Each year, the machinery loses a value of $2,500.
D. Each year, the machinery loses a value of $4,500.
16 / 22

Answer 40

We can see from the graph that the machinery loses $40,000 in value over a period of 10 years. So, on average, it loses $4,000 in value per year.

Therefore, the statement that most closely matches this relationship is: "Each year, the machinery loses a value of $4,000."

The closest answer choice to this statement is (D), which says that the machinery loses a value of $4,500 each year. However, this is not as accurate as the statement that the machinery loses $4,000 each year.

So, the answer is (D), but the more accurate statement is that the machinery loses $4,000 in value per year.

Answer 41

Which of the following is a graph of y = three-halvesx2?
A. This is a graph of a parabola that passes through the points left parenthesis negative 2 comma 2 right parenthesis, left parenthesis 0 comma 0 right parenthesis, and left parenthesis 2 comma 2 right parenthesis.
B. This is a graph of a parabola that passes through the points left parenthesis negative 2 comma 4 right parenthesis, left parenthesis 0 comma 0 right parenthesis, and left parenthesis 2 comma 4 right parenthesis.
C. This is a graph of a parabola that passes through the points left parenthesis negative 2 comma 8 right parenthesis, left parenthesis 0 comma 0 right parenthesis, and left parenthesis 2 comma 8 right parenthesis.
D. This is a graph of a parabola that passes through the points left parenthesis negative 2 comma 6 right parenthesis, left parenthesis 0 comma 0 right parenthesis, and left parenthesis 2 comma 6 right parenthesis.
1

Answer 42

To graph the function y = three-halvesx^2, we can substitute different values of x to find the corresponding values of y.

When we substitute x values from -2 to 2, we get the following y values:

x = -2, y = 6
x = -1, y = 3/2
x = 0, y = 0
x = 1, y = 3/2
x = 2, y = 6

Therefore, the graph of the function would be a parabola passing through the points: (-2, 6), (-1, 3/2), (0, 0), (1, 3/2), and (2, 6).

Out of the given answer choices, the one that matches this graph is (D).

Therefore, the answer is: This is a graph of a parabola that passes through the points left parenthesis negative 2 comma 6 right parenthesis, left parenthesis 0 comma 0 right parenthesis, and left parenthesis 2 comma 6 right parenthesis.

Answer 43

Which equation is true for all x- and y- values in the table below?

x y
1 7
2 14
3 21
4 28
A. y = x + 7
B. y = x – 7
C. y = start fraction x over 7 end fraction
D. y = 7x

Answer 44

To determine the equation that is true for all x- and y-values in the table, we need to look for a consistent pattern in the values.

Looking at the values of y, we can see that they are all 7 times the corresponding value of x. For example, when x = 1, y = 7. When x = 2, y = 14. We can write this relationship as:

y = 7x

Therefore, the correct answer is (D).
