Substitute 0 to x

-7(0)+3y = 30

0 + 3y = 30

Of course, solve for y now

3y = 30

Since the y is multiplied for 3, divide both terms for 3

3y/3 = 30/3

y = 10

What's the sum of 5 feet 9 inches in 12 ft and 3 in
galben [10]
First convert everything into inches.

1 foot = 12 in
5 feet = 5*12 = 60 in
12 feet = 12*12 = 144 in

Now add them together

60 + 9 + 144 + 3 = 216 in

or

18 feet

Hope this helps :)

Answer:

D

Step-by-step explanation:

I think it is D because exponential graphs usually have a curve to them. And the one you need is exponential decay so D is negative and exponential.
