X^2-4x+4 is the answer, to save you points next time, use an app called M8thw8y
I would use a proportion for the Fred's Fouls part. Use the closest point to 12 possible, which is (15, 69.5).
Set up the proportion like so:
15/69.5 = 12/x
Now cross multiply.
15x = 834
Now divide both sides by 15 to get x by itself.
x = 55.6
Fred's Fouls will charge $55.60 for 12 wings.
Now plug in 12 as x for the Carlie's Chicken part and solve for f(12).
f(12) = 3.75(12) +10
f(12) = 45 +10
f(12) = 55
Carlie's Chicken will charge $55 for 12 wings.
When change in one variable is accompanied by the change of another variable in the same direction, they are directly proportional to each other, and it is usually represented by the general equation, y = kx where k is a constant.
Step-by-step explanation:
(1 - cos²A) (1 + tan²A) = tan²A
(sin²A)(sec²A) = tan²A
(sin²A)(1/cos²A) = tan²A
(sin²A)/(cos²A) = tan²A
tan²A = tan²A → <u>Proved</u>
