2(3x - 1) + 2(4x + 5) = 8

x=0

Step-by-step explanation:

2(3x - 1) + 2(4x + 5) = 8

Distribute

6x -2 +8x +10 =8

Combine like terms

14x +8 = 8

Subtract 8 from each side

14x+8-8=8-8

14x =0

Divide each side by 14

14x/14 = 0/14

x=0

Distribute as we get,

Remove the brackets,

Then combine,

Move +8 to the right side and change the +8 to -8 (The operator must be the opposite when move to the other side.)

Move 14 to the right side so we can find the value of x. (Because it's x multiply 14 then 0 will be divided by 14.)

Therefore, x = 0.

a.

step-by-step explanation:

step 1 distribute 2 to every term in the parentheses

step 2 add 10 on both sides of the equal sign

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.
