2r + 2s = 50 and 2r – s = 17. a. r = 3, s = 11 b. r = –8, s = 33 c. r = 14, s = 11 d. r = 25, s = 33

Option C

Step-by-step explanation:

2r+2s=50

2r-s=17

subtract both the equations

you'll get

3s=33

divide 3 on both sides

s=11

substitute s=11 in any of the 2 equations

2r-s=17

2r-11=17

add 11 both sides

2r=28

divide 2 both sides

r=14

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.
