How do I solve it. I don't understand where I should start the problem I have the formulas
anzhelika [568]
Fist you have to find the volume which is 24 x 18 x 5= 2160 feet. 
Then the dump truck can only take 8 cubic yards so then you have to make the 2160 feet into yards. 
There are 3 feet  in one yard so 2160/3=720 
so now there are 720 yards and since the dump truck can only take 8 yards a trip then it would take 90 trips/dumps to empty out the area for the pool.
720/8=90
Hope this helps

Which equation represents a line that passes though (-9,-3) and has a slope of -6
kramer
D) y + 3 = -6(x + 9)



The equation for point-slope form is y - y1 = m(x - x1) where (x1, y1) is a point and m is the slope.

Substitute the values in to get y - (-3) = -6(x - (-9)).

Now, simplify a little bit.

y + 3 = -6(x + 9)

There’s the answer.
