Which equation has the solution x = 3? a. 3x + 1 =9 b. x/3 + 5 = 6 c. 5x - 7= 1 d. 9 - 3x = 0 e. 2x + 4 = 10 f. 9/x - 1 = 4

D.

Equation: 9 - 3x = 0

Subtract 9 from both sides

9 - 3x - 9 = 0 - 9

Simplify

-3x = -9

Divide both sides by -3

-3x / -3  =  -9 / -3

-3x / -3

Apply the fraction rule: -a / -b  =  a / b

= 3x / 3

Divide the numbers: 3 / 3 = 1

= x

Note: x has the same value as 1

Divide the numbers:  -9 / -3 = 3

x = 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 !

i got 10.28 but that rounds up to 10.3
