C-3d = 11
-2c + 3d = -16

This looks like a system of equations:

We should solve for c on the first equation because we can substitute for c. There are a lot of ways we can do a system of equations, but I will do this.

c - 3d = 11

  +3d     +3d

c = 11 +3d

Now we can substitute.

-2(11+3d) + 3d = -16

solve

-22 + -6d + 3d = -16

-22 + -3d = -16

+22             +22

-3d = 6

/-3     /-3

d = -2

So we have found d. We can solve for c.

c - 3(-2) = 11

c + 6 = 11

  -6      -6

c = 5

Now we know both D and C. d=-2 and c=5

the answer is c. 23/3

the correct answer is b. negative exponential growth.

step-by-step explanation:

you can tell it's an exponential function because it decreases rapidly then levels out and never touches the x-axis.

it is negative because the y-axis decreases as the x-axis increases.

therefore it is a negative exponential growth graph.

hope i !
