Suppose y varies at a constant rate of change of 4 with respect to x (so that Ay = 4. Ax), and when x = 1, y = -5. a. If 3 varies from 3 = 1 to 3 = 6, the change in x is:
Az =

dude thats to long figure it

step-by-step explanation:

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

b

step-by-step explanation:

u take $75 minus $60.the anwer/original($75)multiply by 100
