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
Inverse
replace f(x) wih y
solve for x
replace x with f⁻¹(x) and y with x
so
f(x)=3x+5/7
replace
y=3x+5/7
solve for x
minnus 5/7 both sides
y-5/7=3x
divide both sides by 3

=x
replace with f⁻¹(x)
f⁻¹(x)=

is a quadratic function, so its graph is a parabola.
Notice that the coefficient of x is 0, this always means that the axis of symmetry is the y-axis.
That is, the vertex of the parabola is in the y-axis, so the x-coordinate of the vertex is 0.
for x=0, y=-1. So the vertex is (0, -1)
The coefficient of

is negative. This means that the parabola opens downwards, so the vertex is a maximum.
Answer: (0, -1) , maximum (none of the choices)
