Answer:
i think b
Step-by-step explanation:
(2,2). When x of the line is 2, y of the line must be 2.
(-2,-2). When x of the line is -2, y of the line must be -2.
(2,2). y=mx+b or 2=1 × 2+b, or solving for b: b=2-(1)(2). b=0.
(-2,-2). y=mx+b or -2=1 × -2+b, or solving for b: b=-2-(1)(-2). b=0.
The equation of the line that passes through the points
(2,2) and (-2,-2)
is
y=1x
b came out to be zero, so there is no "+b" term.

22.5
Step-by-step explanation:
You can just take 450 calories divided by 20 ounces. 450 divided by 20 is 22.5, so that is the answer.
Answer:
f(-4) = 72, f(x + 5) = 3x² + 23x + 36
Step-by-step explanation:
f(-4) = 3(-4)² - 7(-4) - 4
= 48 - (-28) - 4
f(-4) = 72
f(x + 5) = 3(x + 5)² - 7(x + 5) - 4
= 3(x + 5)(x + 5) - 7(x + 5) - 4
= 3(x² + 10x + 25) - 7(x + 5) - 4
= 3x² + 30x + 75 - 7x - 35 - 4
f(x + 5) = 3x² + 23x + 36
