Please help me solve this problem

Stells [14]

Answer:

$180

Step-by-step explanation:

To solve, we can set up a proportion and solve.

You earn $45 for 7.5 hours of work, and you earn $ x for 30 hours of work

45/7.5=x/30

Cross multiply

45*30=7.5*x

1350=7.5x

To solve for x, we need to get x by itself. It is being multiplied by 7.5. To undo this, divide both sides by 7.5

1350/7.5=7.5x/7.5

180=x

So, for 30 hours of work, you would earn $180

Find an equation for the line perpendicular to y=-1/2x+4 and goes through the point (-1,10)

Artemon [7]

The slope of the perpendicular line will be 2. Remember, a perpendicular slope is the negative reciprocal.

So, we can make the equation $y=2x+b$ . We need to find b, and put b in.

To find b, put in the numbers of y and x.

$10=2(-1)+b$

Solve for b:

$10=-2+b\\b=10+2\\b=12$

Now replace b in the original equation with 12 and that will be the answer:

The answer is $y=2x+12$ .
