Leya [2.2K]

Answer:

15.21

Step-by-step explanation:

All of the bills total to $2432.50. The person works 160 hours in a month. $2432.50 ÷ 160 = $15.20, BUT:

$15.20 × 160 = $2432, which is 50 cents short of what they need, so one extra cent in their wage will give them the amount they need.

$15.21 × 160 = $2433.60

Are the lines parallel, perpendicular, or neither

VikaD [51]

Answer:

perpendicular

Step-by-step explanation:

The first equation can be written in slope-intercept form as ...

y = -1/2x - 3

In this form, we see that the slopes of the two lines are -1/2 and 2, so the product of their slopes is -1. That means the lines are perpendicular.
