You can use substitution for this.
x+5 = 5x -11
Combine like terms
16=4x
Divide 4 on both sides to isolate the x
x=4
Plug x=4 to one of the equations
y= 4 +5
Combine like terms
y=9
So the answer is A. (4,9)
I hope this helps you out a bunch hun :)
Answer:
y=8-x or y=9-x or y=243-x (The spot where the 8 is can be any number as long as the number infront of the 0 is still -1)
Step-by-step explanation:
The meat would end up costing $35 because you want to multiply 
I’m pretty sure it would be f(x)= -5/2x-8
You can honestly plug it into a graph yourself or you can get the formula and solve it like that. Unfortunately I do not have the formula on hand. Sorry
Just take any two points from the graph. For example (4, -2) , (0, -3) Slope = (y2-y1) / (x2-x1) = -2-(-3) / 4-0 = 1/4
