6x-4=2x+8
mnus 2x both sides
4x-4=8
add 4 to both sides
4x=12
divide 4 both sides
x=3
Answer:
D. 31
Step-by-step explanation:
First we need to find what the value of f(2) is, so we are going to substitute x for 2 in f():
f(2)=4(2)^3-10
= 4(8)-10
= 32-10
= 22
And then we substitute 22 for x in g()
g(22)= (3(22)-4)/2
= (66 -4)/2
= 62/2
= 31
Answer:
10+8x
Step-by-step explanation:
x + 20 + 2 (x-5) + 5x This is the problem
x + 20 +2x-10 + 5x You distribute the 2
From here you just combine the similar numbers. "x"s plus "x"s and ones without "x"s plus each other
x + 10 +2x + 5x 20-10 gets you 10
10 + 8x 5x+2x gets you 7. From that point x equal 1 (or 1x) and you get the answer of <u>10 + 8x</u>
