Step-by-step explanation:
sqrt{64} is 8 (8*8)
p(10) is the profit, in dollars, from selling 10 books. Replace every copy of x with 10 and simplify
p(x) = 8x-10
p(10) = 8*10-10 .... every x is replaced with 10
p(10) = 80-10
p(10) = 70
So the profit is $70
Answer:

Step-by-step explanation:
Just so you know, there is a thing called calculator
You should really get one if you are asking such questions
Or maybe, IDK maybe DON'T BE LAZY AND LEARN TO DO SIMPLE CALCULATIONS
answer:
x=-4/7 and the slope is 7
{(V-v)*2=86(mi)
{(V+v)*2=110(mi)
{(V-v)=43
{(V+v)=55
2V+v-v=43+55
2V=98
V=49(mph)
v=55-49=6(mph)
