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.

The force F (in pounds) required to push a sofa across a floor varies directly as the weight w (in pounds) of the sofa.

djyliett [7]

Answer: $F=0.41w$

Step-by-step explanation:

1. You know that the force F varies directly as the weight w of the sofa. Then, you can write the following expression:

$F=kw$

Where k is the constant of proportionality.

2. You know that a person can push a 120 pound sofa with a force of 50 pounds, then you can calcualte the constant of proportionality as following:

$k=\frac{F}{w}=\frac{50lb}{120lb}=0.41$

3. Then, the equation is:

$F=0.41w$

Given the following perfect square trinomial, fill in the missing term. x2 − 16x + ____

pychu [463]

The pattern is:
( a - b )² = a² - 2 a b + b² ( square of last term of binomial - the missing term)
x² - 2 · 8 · x + 8² = x² - 16 x + 64 = ( x - 8 )²
The missing term is: 64
