Answer:

I believe x = 2.

Use distributive prop. to get rid of parentheses:

3x-12=-4x+2

Move the -12 over to the other side. Since everything that goes to the other side changes signs, the "-" sign will change to a "+" sign. Move the -4x to the other side as well. Remember to change the sign!

3x + 4x = 2 + 12

Now combine like terms:

7x = 14

To get the x fully isolated, we need to divide both sides by 7 so we can get rid of the 7.

7x/7 = 14/7

x = 2

Hope this helped! :)

PLEASE HELP WILL GIVE BRAINLIEST TO CORRECT ANSWER

ioda

Answer:

Step-by-step explanation:

h(x) = 7 - x - 2x^5

h(-1) = 7 + 1 - 2(-1)^5

h(-1) = 7 + 1 + 2

h(-1) = 10

Now differentiate h(x)

h'(x) = -1 - 2*5*x^4

h'(x) = -1 - 10x^4

h'(x) = -1 - 10(x)^4

h'(x) = -1 - 10 (x)^4

h'(-1) = -1 - 10(10000)

h'(-1) = -1 - 100000

h'(-1) = - 99999
