edge length is 40 inches.
The edge length of a cube has the same measurement.
Volume of a cube is computed by multiplying the edge length to itself twice.
Volume = edge length x edge length x edge length
If the given data is volume of the cube and edge length is required. simply find the cube root of the volume.
edge length = ∛volume
edge length = ∛64000 in³
edge length = 40 inches.
To check:
40 x 40 = 1600 x 40 = 64000
The slope is 1. The line first crosses the y axis at -5. So the answer is...
y = 1x + -5
101.7755814 miles for only 8.03 gallons
-8
2/3(-21/3) + 2/3(-15/3)
-42/9 + -30/9
-72/9 = -8
That line is in point-slope form:

Where 'm' is the slope and (x1, y1) is a point on the line.
Perpendicular lines have opposite slopes. To get the opposite, we take the reciprocal and multiply it by -1.

Reciprocal:

Multiply by -1:

We can plug this slope and the point into point-slope form, and then convert it to slope-intercept form.


Negatives cancel out:

Distribute 1 into the parenthesis:

Subtract 2 to both sides:
