You have to read 15 pages of a novel for homework. The number of pages p(x), that you have left to read after reading for x minutes is given by p(x) = -x + 15. What is p(7)

a.) 7
b.) 8
c.) 15
d.) 22

I think the answer may be 8, would this be correct?

yes

Thanks :)

To find the value of p(7), you need to substitute the value of x = 7 into the equation p(x) = -x + 15.

So, substitute x = 7 into the equation:

p(7) = -(7) + 15

Now solve this equation:

p(7) = -7 + 15

p(7) = 8

Therefore, based on the given equation, the value of p(7) is 8.

So, your answer is correct. The answer is b) 8.
