Answer:
A
Step-by-step explanation:
A function composition is where one function is substituted within another function and is written g(f(x)). Here we will substitute f(x) into g(x). For g(f(-7)), we substitute -7 for x.
Now substitute -7 for x.
Answer:
2²×3³
Step-by-step explanation:
162 can we shown as:
81*2=162 as 2 is prime we leave it out and focus of 81:
18*3=81 we leave out 3:
3*6=18 we leave out 3 again:
3*2=6
so our answer is 2*2*3*3*3 which in index form is 2²*3³ as there are two 2s and three 3s.
Answer:
2x²+x-15=0
Step-by-step explanation:
A=L×W
12cm²=(2x+3)(x-1)
12=2x²-2x+3x-3
12=2x²+x-3
2x²+x-3-12=0
2x²+x-15=0
I believe the answer is .85
Answer:
x=13
Step-by-step explanation:
Simplifying
8 + 2x = 34
Solving
8 + 2x = 34
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-8' to each side of the equation.
8 + -8 + 2x = 34 + -8
Combine like terms: 8 + -8 = 0
0 + 2x = 34 + -8
2x = 34 + -8
Combine like terms: 34 + -8 = 26
2x = 26
Divide each side by '2'.
x = 13
Simplifying
x = 13
