A. Harry started a new job where he earns the same amount every hour. Last week, he worked 9 hours and
earned $108. Write the linear equation for this situation in the box below, where y represents the money.
earned, in dollars, and a represents the number of hours worked.

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional

answer:

a=9

step-by-step explanation: lmk if you need a explanation

answer: translate the circles so they share a common center point and dilate circle y by a scale factor of 3.
