AleksandrR [38]

Answer:

0 = -8t + 96\\\\\Rightarrow\ 8t=96\\\\\Rightarrow\ t=\dfrac{96}{8}\\\\=12

<h3>Hence, it will take 12 minutes by the printer to use all 96 sheets of paper.</h3>

Step-by-step explanation:

Given :

Tanya is printing a report.

There are 96 sheets of paper in the printer, and the number of sheets of paper p left after t minutes of printing is given by the function

p(t) = -96 - 8t

When all the 96 sheets printed , then the number of sheets will left to print =0

Substitute p(t)=0 in the given function, to find the value of t, we get

0 = -8t + 96\\\\\Rightarrow\ 8t=96\\\\\Rightarrow\ t=\dfrac{96}{8}\\\\=12

<h3>Hence, it will take 12 minutes by the printer to use all 96 sheets of paper.</h3>

Let 2x-5y=16 and 5x+3y=9. what is the value of 12x+y
kari74 [83]
2x-5y=16    =>10x-25y=80
5x+3y=9     => 10x+6y=18
subtract one from the other: (6-(-25)y=(18-80), 31y=-62, y=-2
plug y=-2 in 2x-5y=16 to find x: 2x+10=16, x=3
12x+y=12*3-2=34
