Answer:
B. Distance formula because this statement tells the length of these segments which can be calculated by the distance formula.
Answer:
-5, -1.3, 0, and 0.9
Step-by-step explanation:
Inverse variation is of the form y=k/x, or if you prefer yx=k. "Inverse" variation because as x increases, y decreases...Anyway the equation can be expressed as:
y=k/x, we are given one point (10,8) so we can find the value of k, the constant of variation using those coordinates...
8=k/10 multiply both sides by 10
80=k so the equation is:
y=80/x
That is where the function equals 0
0=5x-20
add 20 both sides
20=5x
divide 5
4=x
the zero is at x=4
(4,0)
Answer:
Here is a generic way to set up this type of algebra problem.
d = total amount of dirt at the site (tons)
r = rate or removal (tons/hr)
t = time it takes to remove all of the dirt (hr)
d = rt
The total amount of dirt equals the removal rate times hours spent removing all the dirt.
Since you want to solve for t, divide both sides by r
t = d/r
