Which of the following represents a proportional function? A. the amount of money on a gift card, if the original amount is $200 and $50 is spent once a week for 4 weeks

B. the savings in a bank account, if $100 is initially deposited and $25 is deposited each week afterwards

C. the amount of money charged for a hotel room, if the cost is $86 per day

D. the amount of money that is charged for a cleaning service, if the cost is $25 per visit, plus $15 for each hour of work

I need this ASP please help!

.there can be infinite values of m and n that can satisfy the above equation. for each value of m of m or n. there maybe infinite sets of solution for the above

step-by-step explanation:

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
