- Frederick earns $10 per hour at the grocery store.
- He earns $8.50 per hour mowing lawns.
- He worked 35 hours last week.
represents hours mowing lawns, which make him earn $8.5 each.
represents the total earnings, mowing lawns plus grocery store.
Now, we know that he worked 35 hours in total. So, if he worked mowing lawns, then he worked
hours in the grocery store, which represents +$10 per hour. So, this situation can be expressed as
Then, we solve the operations
Therefore, the right choice is B. y = -1.5x + 350

Answer:
38.5°
Step-by-step explanation:
A triangle solver can give an answer easily. The angle is 38.5°.
__
The law of cosines can be written to solve for an unknown angle C opposite side 'c' and flanked by sides 'a' and 'b'.
C = arccos((a² +b² -c²)/(2ab))
Here, we have a=35, b=48, c=30, so the angle is ...
C = arccos((35² +48² -30²)/(2·35·48)) = arccos(2629/3360) ≈ 38.515°
The angle the cable makes with the pole is about 38.5°.
