If <span>y = -x + 7, and (-1,y) is on the graph, then the following is true: y=-(-1) + 7, or y=8.
Thus, y = a0 = 8.</span>
{-2x-5y=13
<u>{2x-5y=17 </u>(+)
<em /> -2x+2x-5y-5y=13+17
-10y=30 /:(-10)
y=-3
2x-5y=17
2x-5*(-3)=17
2x+15=17
2x=2
x=1
<em>Solution: (1; -3)</em>
You set it up as a y=mx+b problem 150=55x+40 then you subtract 40 from 150 making 110=55x so x=2
"the following" of what? I think you are missing the list
Answer:
8 Shampoo Concentrate
Step-by-step explanation:
There's a ratio of 9:2 so for every 9 cups of water there's two cups of shampoo concrete.
We'll need 9 multiplied by 4 is 36
so we need to multiply 2 with 4
4 multiplied by 2 is 8
