Evaluate r(x) = -x -7 when x = -2, 0, and 5

The values of r(x) for x = - 2, 0 and 5 are obtained by Substituting the values for x in the function, hence the values are :

When x = - 2

When x = 0

When x = 5

Therefore, the required values are - 9, - 7 and - 2

r(-2) = -5 , r(0) = -7 , r(5) = -12

Step-by-step explanation:

Plug in the numbers for x and then solve. : )

r(-2) = - (-2) - 7

r(-2) = 2 -7

r(-2) = -5

r(0)= -0 -7

r(0)=0-7

r(0) = -7

r(5) = -5 - 7

r(5) = -12

the answer to the question is a

step-by-step explanation:

it has the same slope and the same y-intercept.

y + 11 = -7/9(x - 18)

y + 11 =-7/9x + 14

b

y = -7/9x + 3

y-intercept (0, 3)

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
