Answer:
3240 in^3
Step-by-step explanation:
Step one:
given data
The dimension of the form
Length 40 and 1/2 inches long,
Depth 10 inches deep,
The width and 8 inches high
Step two:
The amount of cement is equivalent to the volume of the form

Hence the volume of cement is 3240 in^3
Given

I attached a graphical solution to the equation. The blue curve represent

while the red curve represent

From the equation, it can be seen that the curves representing the two terms in both sides of the equation does not meet.
Therefore, the statement about the graph that is true is "The curves do not intersect".
Answer:
y=-x-4
Step-by-step explanation:
You can write the equations in point-slope form first.
1) y+3=-(x+1)
2) Then you can convert it into slope intercept form
3) y=-x-1-3
4) y=-x-4
