Step-by-step explanation:
volume of concrete=162×12×4/12=648 ft³
y=-2x+2
y=7x+11
Answer:
(-1, 4)
Step-by-step explanation:
We are told that:
y = -2x + 2 and
y = 7x + 11.
We can eliminate "y" by setting these two equations = to each other:
-2x + 2 = 7x + 11.
We need to solve this equation for x.
Adding 2x to both sides, we get 2 = 9x + 11.
Subtracting 11 from both sides results in -9 = 9x. Thus, x = -1.
Find y by subbing -1 for x in either of the given equations.
If we use the 2nd equation, then y = 7(-1) + 11, or y = 11-7, or y = 4.
The solution of this system of linear equations is (-1, 4)
