5(4x-10)+10x = 4(2x-3)+ 2(x-4)? is equal to - 7/4 or - 1/4 or 3/20 or 3/2 ?

x is equal to 3/2

Step-by-step explanation:

Let's solve it!

5(4x - 10) + 10x = 4(2x - 3) + 2(x - 4)

expand:

20x - 50 + 10x = 8x - 12 + 2x - 8

group like terms:

30x - 50 = 10x - 20

factor out common multiples:

3x - 5 = x - 2

group terms again:

3x - x = -2 + 5

2x = 3

and divide both sides by two:

x = 3/2

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.
