The answer is given by the empirical rule, 68%.
Step-by-step explanation:
This can be modeled by the equation f(x)=7+5x
Because if f(1)=7+5=12, f(2)=7+10=17, and f(x)=7+15=22
If x=50 then f(50)=7+5(50)
f(50)=$257

Answer: G) -2</h3>
=======================================================
Explanation:
I'm assuming you meant to say (a+y)^2 + 2y
Replace each copy of 'a' with 5. Replace each copy of 'y' with -3. Use PEMDAS to simplify.
(a+y)^2 + 2y
(5 + (-3))^2 + 2(-3)
(5-3)^2 + 2(-3)
(2)^2 + 2(-3)
4 + 2(-3)
4 - 6
-2
So (a+y)^2 + 2y = -2 when a = 5 and y = -3.
