Answer:

21=2x+4

x=$8.5

Step-by-step explanation:

We know that the pay the student earns at an internship will add up to $21 and is therefor less. This means that the equation must be 21=2x+4 where x is the internship money. We solve for x to find how much the student makes at the internship.

21=2x+4

21-4=2x+4=4

17=2x

8.5=x

vovikov84 [41]

Answer:

(-6, -4).

Step-by-step explanation:

When you reflect coordinates over the y-axis, the x-coordinates remain the same, but the y-coordinates become their additive inverse.

The original coordinates for F are (6, -4).

The new coordinates for F would be F' (-6, -4).
