Answer:
the = sign means both sides of the equation have the same value.
The red line is y=1/2x -4 while the blue one is y=-2x+1. It's the last statement
Answer:
f(1) = 9
Step-by-step explanation:
Evaluate f(x) = 4x+5 by replacing both instances of x with '1' as follows:
f(1) = 4(1) + 5 = 9
Thus, f(1) = 9
Step-by-step explanation:

So sqrt(40) lies between 6 and 7.
The correct factorization is
2(x-2)²
