I usually use the equation y=mx+b if that helps..
It’s basically the same thing as NP so it’s D.9
The equation must equal 84, so you can eliminate B and D.
Chin charges a rate for 2 hours, then charges a reduced rate for 4 hours. There are no discounts present in his rate, so you can eliminate A.
The equation for Chin's charges can be found by the equation C. 2x + 4y = 84.
Answer:
Explanation: Note that
To evaluate the integral in the boxed equation, let
. Then,
So,
Since y = 1 when x =0, equation (1) becomes
With the value of C, equation (1) becomes
Hence, if y = 3,
