What is the value of the function y=18x−13 when x=−4 ?(1 point) Responses: −12.5 negative 12.5 −15 negative 15 −16 negative 16 −13.5

Answer 1

To find the value of y when x = -4, we substitute -4 for x in the equation y = 18x - 13:

y = 18(-4) - 13
y = -72 - 13
y = -85

Therefore, the value of the function y = 18x - 13 when x = -4 is -85.

Answer 2

Which of the following is an ordered pair of the relation y=−23x+6 ?(1 point)

Answer 3

To find an ordered pair for the relation y = -23x + 6, we need to substitute values for x and solve for y.

Let's check each option:

A) (-1, 29)
Plugging in x = -1:
y = -23(-1) + 6
y = 23 + 6
y = 29

B) (3, -69)
Plugging in x = 3:
y = -23(3) + 6
y = -69 + 6
y = -63

C) (0, 6)
Plugging in x = 0:
y = -23(0) + 6
y = 0 + 6
y = 6

D) (-2, 52)
Plugging in x = -2:
y = -23(-2) + 6
y = 46 + 6
y = 52

Therefore, the ordered pair (0, 6) is the correct answer for the relation y = -23x + 6.

Answer 4

Which of the following is an ordered pair of the relation y=−23x+6 ?(1 point) Choices: A. (3,8) B. (1,4) C. (0,−23) D. (3,4)

Answer 5

To find an ordered pair for the relation y = -23x + 6, we need to substitute values for x and solve for y.

Let's check each option:

A) (3, 8)
Plugging in x = 3:
y = -23(3) + 6
y = -69 + 6
y = -63

B) (1, 4)
Plugging in x = 1:
y = -23(1) + 6
y = -23 + 6
y = -17

C) (0, -23)
Plugging in x = 0:
y = -23(0) + 6
y = 0 + 6
y = 6

D) (3, 4)
Plugging in x = 3:
y = -23(3) + 6
y = -69 + 6
y = -63

Among these options, the ordered pair (0, -23) is the correct answer for the relation y = -23x + 6. Therefore, the answer is C. (0, -23).
