Denise gets paid $600 an hour plus $430 commission on her sales. If her paycheck this week was $700, how many hours did she work?

you have to find the same variables -3n - 5n so this would be -3n +(-5n) which equals -9n

place r′ so that qr′ is parallel to the tangent.

now we get that ∠r′py=∠pr′q, where y is on the tangent, on the opposite side of p from x.

also, because of the symmetry, ∠r′py=∠qpx.

finally, note that no matter where we place r, as long as it's on the correct arc, we have ∠prq=∠pr′q.

stringing all these equalities together, we end up with ∠prq=∠qpx.

this picture will show how its going to look like.

hope this by jack monhen
