We are told that f(x) = x + 2. We want to find .
Squaring f(x) on one side means we square x + 2 on the other.
So,
f(x) = x + 2
(f(x))² = (x + 2)²
= (x + 2)(x + 2)
We can use FOIL to square x + 2. The first terms multiply to x², the outside terms to 2x, the inside terms to 2x and the last terms to 4.
= x² + 2x + 2x + 4
= x² + 4x + 4
So [f(x)]² = x² + 4x + 4
Answer:
C. x + 6
Step-by-step explanation:
Start by factoring completely the numerator and the denominator.
2x + 12 = 2(x + 6)
x^2 + 7x + 6 = (x + 1)(x + 6)
The only common factor is x + 6, so the GCF is x + 6
Do u mean hundredth? If so it’s 24.6
Answer:
18
Step-by-step explanation:
In the linear regression equation y=a+bx, slope coefficient b represents average unit increases in y variable due to unit increase in x variable.
In the given equation ŷ = 84 + 18x, b=18 represents average unit increases in gas used due to unit increase in degree day.
Hence,on average, gas used increase by 18 for each additional degree-day.
Hello,
Perpendicular sloop m is : 4*m=-1==>m=-1/4
Equation 's line is y-3=-1/4(x-8) or y=-x/4+5
