Kira’s monthly gym bill is $50 plus $15 per class. She signs up for at least one class each month. Write a linear function to represent Kira’s gym cost. What do the domain and range of the function represent?

constants mean the stopped points or the points on a graph that nothing is changing, hope this

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

the answer is b

im guessing (23,14). hope this : )
