I REALLY NEED HELP FAST 20 POINTS!

1. Which of the following is a proportion?

a. 9/12 = 8/10
b. 12/18 = 9/16
c. 3/4 = 9/12
d. 6/8 = 8/12

2. What is the scale factor?

c=3/4=9/12

Step-by-step explanation:

9/12 dividing by 3

we get 3/4

LHS=RHS

hence c is your answer

A scale factor is a number which scales, or multiplies, some quantity. In the equation y = Cx, C is the scale factor for x. C is also the coefficient of x, and may be called the constant of proportionality of y to x.

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value
