Rewrite it as y=6x-7/5
Flip the x and y
x=6y-7/5
Solve
5x=6y-7
5x+7=6y
5/6x+7/6=y
f^-1(x)=5/6x+7/6
Answer:
106250
Step-by-step explanation:
Ok so we know that in the first quarter the company sold 125000 units to people. But then suddenly they start losing 5%. Since we are told there are 3 quarters, we would have to do 5% plus 5% plus 5%, which amounts to 15% total lost in the three quarters. What we do now is we technically subtract that to 125000, so the equation would be 125000 minus 15%, and when you either use a calculator to help or your own mind, you get 106250 units sold.
That would be 20/120 or reduced to 1/6, C.
5x630=3150. 3150-2910=240. 240/3=80. There were 80 kids.
(85 + 60) ÷ 2 = 72.5 Close to 71%
Answer: D - 71%
