Answer 4

The graph that best represents the equation y + 7 = |x + 5| is:
An absolute value function is graphed on a coordinate plane. Its vertex is 5 comma -7. It passes through the points (2, -4) and (8, -4).

Answer 5

To determine if y varies directly with x, we need to check if the ratio between y and x remains constant.

We can find the constant of variation, k, by dividing two sets of corresponding values for y and x.

Looking at the given values:

x: 7, 11, 18, 13, 9, 15, 10, 17
y: 19, 15, 19, 15, 5, 15, 10, 17

Let's calculate the ratios:

19/7 ≈ 2.714
15/11 ≈ 1.364
19/18 ≈ 1.056
15/13 ≈ 1.154
5/9 ≈ 0.556
15/15 = 1
10/10 = 1
17/17 = 1

The ratios are not equal; therefore, y does not vary directly with x. There is no constant of variation, and we cannot write an equation for this relationship.

Answer 6

To write a linear equation to model the relationship between the height h of the candle and time t, we can use the two given data points.

Let's set up a slope-intercept form equation, y = mx + b, where y is the height h of the candle and x is the time t.

Given data points:
(3, 17)
(5, 15)

We can find the slope (m) using the formula:

m = (y2 - y1) / (x2 - x1)

m = (15 - 17) / (5 - 3)
m = (-2) / 2
m = -1

Now we can substitute one of the given points and the slope into the equation y = mx + b to find the y-intercept (b).

Using the point (5, 15):

15 = -1(5) + b
15 = -5 + b
b = 20

So the equation that models the relationship between the height h of the candle and time t is:

h = -t + 20

To predict the height of the candle after burning for 8 hours, we substitute t = 8 into the equation:

h = -(8) + 20
h = 12

Therefore, the candle will be 12 inches tall after burning for 8 hours.

Answer 7

To translate the graph of f(x) = x^2 to the left 8 units and up 2 units, we need to adjust the function rule for g(x) accordingly.

The translation to the left by 8 units is represented by (x + 8), and the translation up by 2 units is represented by +2.

Therefore, the function rule for g(x) is:

g(x) = (x + 8)^2 + 2

This means that g(x) is the result of taking the function f(x) = x^2 and shifting it 8 units to the left and 2 units up.
