Answer:
A) 9
Step-by-step explanation:
f(2) is basically asking what the y-coordinate is at x = 2
If you trace x = 2, you see it intersects f(x) at (2, 9).

Answer:
23x = -115
Step-by-step explanation:
In the substitution method, you must solve for 1 variable in 1 equation to replace it in the other equation. For the system:
2x - 7y = 4
3x + y = -17
Solving for y in the second equation:
y = -17 - 3x
Replacing y in the first equation:
2x - 7(-17 - 3x) = 4
2x + 119 + 21x = 4
23x = -115
This is the new equation after use the substitution method.
Answer:
(x + 2)^2 - 1
Step-by-step explanation:
x^2 + 4x + 1
= (x^2 + 4x + 2 - 2 + 1)
= (x + 2)^2 - 1
