Taking test right now please help!!
Substitute the given values of the variables into the equation. Write True or False to indicate whether the values make the open sentence true or false. Values: x=9 ,y=0.4, z=22
2x + 0.8/y = z - 4

answer:

False

Step-by-step explanation:

2(9) + 0.8/(0.4) = (22) - 4     Substitute in the values

18 + 2 = 22 - 4                      Multiply

20 = 18                                  Simplify

Because 20 is not equal to 18, the equation is false.

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 !
