f(x) = 112 - kx
f(-3) = 112 - k(-3)
f(-3) = 112 - (-3k)
f(-3) = 112 + 3k
121 = 112 + 3k
- 112 - 112
9 = 3k
3 3
3 = k
Let, one leg be x units.
since the other leg is 9.0 units shorter than the other,
the measure of the other leg =x-9
hypotenuse =13.0 units
According to Pythagorean theorem, the square of the hypotenuse is equal to the sum of squares of the other two sides.
x^2 +(x-9)^2 =13^2
x^2 + x^2 -18x +81 = 169
2x^2-18x-88=0
Divide the whole equation by 2
x^2 - 9x -44 =0
Let's use the quadratic formula to find the roots.
formula: x= [-b ± sqrt(b^2-4*a*c)]/2*a
a=1 b=-9 c=-44
x= [9±sqrt(81+176)]/2
=[9±sqrt(257)]/2
=[9±16.03]/2
=25.03/2 or -7.03/2
length of a triangle cannot be negative,
Therefore, x=25.03/2 =12.52
one leg =12.5 units
other leg =12.52-9 =3.5 units

Answer:
The unit cost per ounce for turkey skylar is $ 0.316
Step-by-step explanation:
The total amount of sliced turkey = 5 pounds + 4 ounces
The total cost of turkey slice = $26.88
Now, as we know
1 pounds = 16 ounces
∴ 5 pounds = 16 × 5 = 80 ounces
So, the total amount is 5 pounds + 80 pounds = 85 pounds
∵ 85 pounds of turkey sliced cost $ 26.88
∴ 1 pounds of turkey sliced cost $ 
= $ 0.316
Hence the unit cost per ounce for turkey skylar is $ 0.316 Answer
