The answer to the question is 229
A = 210 + 20(h - 7) <== ur equation
if she earns 410 tutoring...
410 = 210 + 20(h - 7)
410 = 210 + 20h - 140
410 = 20h + 70
410 - 70 = 20h
340 = 20h
340/20 = h
17 = h <=== she spent 17 hrs tutoring
13/20 or percentage would be 65% :))
Assuming that the x is not part of the ^-1 the range would be
[0,π/2) U (π/2,<span>π]</span>
Answer:
0 solutions
Step-by-step explanation:
