Which statement best describes the function below?

harina [27]

Answer:

D. It is a many-to-one function

Step-by-step explanation:

One-to-one if every y value has exactly one x value mapped onto it
Many-to-one if there are y values that have more than one x value mapped onto them.

We have a function that is of degree 3, so it has 3 x-intercepts which means there are points (x₁, 0), (x₂, 0), (x₃, 0), so it is a many-to-one function

Correct option is D

joe and Eric have to ship 75 packages. Joe can do the job alone in 5 hours. if Eric helps, they get it done in 4 hours. How long

Umnica [9.8K]

Eric took 20 hours to do the job alone.

Step-by-step explanation:

Given :

Total work = 75 packages
Joe took 5 hours to complete the total work.

The amount of work Joe alone can do per hour = 75/5 = 15 packages.

The amount of work Joe and Eric together do per hour = 75/4 = 18.75

The amount of work Eric alone can do per hour = 18.75 - 15 = 3.75

The time Eric took to complete the entire work = 75 / 3.75 = 20 hours.

What is the midpoint of a segment with These endpoints (-12,-3) and (3,-8)

Savatey [412]

Answer:

$(\frac{-9}{2},\frac{11}{2})$

Step-by-step explanation:

you have to use the midpoint formula which is

$(\frac{x1+x2}{2},\frac{y1+y2}{2})$

so you plug your numbers in

$(\frac{-12+3}{2},\frac{-3+-8}{2})$

Add the tops

$(\frac{-9}{2} ,\frac{-11}{2} )$

if possible simplify

and that is your answer
