I'm guessing the answer is B? I tried to isolate r and I got that result. Sorry if it's wrong!
just use a calculator next time then
They bowled for 3 hours and spent $7.
(I have no Idea how to make a graph on this website, so I can't help you there, sorry)
Let x = number of hours
Tucker: 2x+1
Blanca: x+4
2x+1 = x+4
x=3
For the graphs your lines should have equations like this:
y= 2x+1
y=x+4
The point of intersection of these lines should be at point (3,7)
Answer:
the third term wasn't distributed properly the -2 has to multiply by +2 = -4
Step-by-step explanation:
-5x^2y - 3xy^2 - 2(4y+2) - 2.5x^2y
-5x^2y - 3xy^2 - 8y - 4 - 2.5x^2y
-7.5x^2y - 3xy^2 - 8y - 4
