Answer:
x = ±11i
Step-by-step explanation:
x^2 = -121
Take the square root of each side
sqrt(x^2) = sqrt(-121)
sqrt(x^2) = sqrt (-1) *sqrt(121)
We know that the sqrt(-1) is i
x = i ( ±11)
x = ±11i

t is the number of hours Lamar worked as a tutor
We know that he worked for 92 hours total, so he worked 92-t hours as a waiter.
So his earnings are: 7t + 8(92-t) = 736 -t dollars
This expression seems logical as if Lamar worked 0 hours as a tutor and 92 as a waiter his earnings would be 8*92 = 736
If he worked as a tutor for 92 hours it would be 7*92= 644
736-92= 644
So our expression seems to be working.
