We are given with two functions: f(x) = x + 8 and g(x) = x2 - 6x - 7. In this problem, the value of f(g(2)) is asked. We first substitute g(x) to f(x) resulting to f(x2 - 6x - 7) = x2 - 6x - 7 + 8 = x2 - 6x + 1. If x is equal to 2, then <span>f(g(2)) = 2^</span>2 - 6*2 + 1 equal to -7.
Answer:
(f * g)(x) has a final product of 16x² + 8x.
Step-by-step explanation:
When you see (f * g)(x), this means that we are going to be multiply f(x) and g(x) together.
<em>f(x)=8x</em>
<em>g(x)=2x+1</em>
Now, we multiply these terms together.
(8x)(2x + 1)
Use the foil method to multiply.
16x² + 8x
So, the product of these terms is 16x² + 8x.
Answer: X=1.5
Step-by-step explanation:
Solution
Perimeter= 2(l+w)
25= 2( 3x+4 +2x+1)
25= 2(3x+2x+4+1)
25= 2(5x+5)
25= 10x+10
Now subtract 10 on both sides..
25-10= 10x+10-10
15=10x
Now divide 10 on both sides to get x
15/10= 10x/10
1.5=X
Answer
Answer:
Option D, x = 4
Step-by-step explanation:
Option A: y = 4 doesn't work because that line would be horizontal
Option B: y = 4x doesn't work because that would be diagnol
Option C: x = -4 doesn't work because that would a vertical line at -4
<em>Option D: x = 4 works because that would a vertical line at 4</em>
<em />
Answer: Option D, x = 4
Answer:21x^2-16x-16
Step-by-step explanation:
(3x)(7x)+(3x)(4)+(−4)(7x)+(−4)(4) =
21x^2+12x−28x−16
21x^2−16x−16
