To find the output of the function y = 3x + 6 when the input is x = 0.3, substitute 0.3 for x:
y = 3(0.3) + 6
y = 0.9 + 6
y = 6.9
Therefore, the output of the function is y = 6.9. The answer is D.

To find the value of the function y = (1/8)x - 13 when x = -4, substitute -4 for x:
y = (1/8)(-4) - 13
y = -4/8 - 13
y = -1/2 - 13
y = -1/2 - 26/2
y = -27/2
y ≈ -13.5
Therefore, the value of the function is approximately -13.5. The answer is A.
y = (1/8)(-4) - 13
y = -4/8 - 13
y = -1/2 - 13
y = -1/2 - 26/2
y = -27/2
y ≈ -13.5
Therefore, the value of the function is approximately -13.5. The answer is A.
The graph of a relation is given apply the vertical line test to determine if the relation is a function
A the relation is a half Circle
B there is not enough information to determine whether this relation is a function
C the given relation is not a function
D yes, the given relation is of function
A the relation is a half Circle
B there is not enough information to determine whether this relation is a function
C the given relation is not a function
D yes, the given relation is of function
If the graph of a relation is a half circle, applying the vertical line test will help determine if the relation is a function.
The vertical line test states that a relation is a function if every vertical line intersects the graph at most once.
In the case of a half circle, any vertical line will intersect the graph at two points, one on the top half and one on the bottom half. Therefore, the relation is not a function.
The correct answer is C: the given relation is not a function.
The vertical line test states that a relation is a function if every vertical line intersects the graph at most once.
In the case of a half circle, any vertical line will intersect the graph at two points, one on the top half and one on the bottom half. Therefore, the relation is not a function.
The correct answer is C: the given relation is not a function.
Which of the following is an ordered pair of the relation Y equals -2 over 3X +6
A 3,8
B 3,4
C 1,4
D 0,-2/3
A 3,8
B 3,4
C 1,4
D 0,-2/3
To find the ordered pair of a relation, substitute the given values of x and y into the equation and see if they satisfy the equation.
For the given equation y = -2/3x + 6, let's check the options:
A: y = -2/3(3) + 6 = -2 + 6 = 4, which is not equal to 8. This is incorrect.
B: y = -2/3(3) + 6 = -2 + 6 = 4, which is equal to 4. This is correct.
C: y = -2/3(1) + 6 = -2/3 + 6 = 18/3 - 2/3 = 16/3 ≠ 4. This is incorrect.
D: y = -2/3(0) + 6 = 0 + 6 = 6, which is not equal to -2/3. This is incorrect.
Therefore, the ordered pair that is a solution to the equation y = -2/3x + 6 is 3,4. The correct answer is B.

Therefore, the ordered pair that is a solution to the equation y = -2/3x + 6 is 3,4. The correct answer is B.
Which of the following gives an example of a function that is not linear

A linear function is a function that can be represented by a straight line.
Let's analyze the options:
A: y = (1/6)x + (2/3). This is a linear function, as it can be represented by a straight line.
B: 2x + 3y = 16. This is a linear function, as it can also be represented by a straight line.
C: 9x + 3y - (-18) = 0, which simplifies to 9x + 3y + 18 = 0. This is also a linear function.
D: y = x^2 - 3x + 2.5. This is not a linear function, as it contains a squared term (x^2), which represents a curve. It cannot be represented by a straight line.
Therefore, the correct answer is D: y = x^2 - 3x + 2.5, as it gives an example of a function that is not linear.
