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
Answer:
(0, 7), (1, 11), (2, 15)
Step-by-step explanation:
to find the y values, plug in the given x values into the equation y= 4x+7
when x = 0
y = 4(0) + 7
y = 0 + 7
y = 7
so the y value that corresponds to the x value 0 is 7 which is also written as (0,7)
when x = 1
y = 4(1) + 7
y = 4 + 7
y = 11
so the y value that corresponds to the x value 1 is 11; also written as (1, 11)
when x = 2
y = 4(2) + 7
y = 8 + 7
y = 15
so the x value 2 corresponds to the y value 15; also written as (2 , 15)

Answer:
X=1
Step-by-step explanation:
Solve for the vertex of the parabola: (v)
The axis of symmetry for a parabola will always be x=v.
Graphing the function shows the vertex at (1,-9) so the line denoting the axis of symmetry will be x=1.
