We know for our problem that Rachel makes $10 per hour. Since
represent the number of hours that she works,
will be the total amount that she will make for working
hours. We also know that she sells bracelets for $5 each. Since
represents the number of of bracelets that she sells,
will be her total revenue for selling
bracelets. We also know that she needs to earn at least $200 a week to cover her expenses, so the sum of
and
must be equal or greater than 200:
We can conclude that <span>the graphs that shows the inequality that represents this situation, with its solution region shaded is:</span>
Answer:
Step-by-step explanation:
The tangent is perpendicular to the radius. The given triangle is right if AB is tangent.
Use Pythagorean to verify
- 20² = 16² + 12²
- 400 = 256 + 144
- 400 = 400
Confirmed
