Answer:
B. Perfect Cube
Step-by-step explanation:
A perfect cube is a number whose cube root is a whole number.
5^3 = 125
Answer:
To do this, you imagine a vertical (up and down) line moving across your graph from left to right. It should only be touching the line at one point at a time. If it is touching more than one point on the line at a time, the line is not a valid function. The first line and its inverse both pass the test.
Step-by-step explanation:
Plan 1 costs $34.99 per month.
For 12 months, it would cost 12 * $34.99 = $419.88
Plan 2 cost $134.97 for 3 months.
A year is 12 months, so it has 4 periods of 3 months.
In one year, this plan would cost 4 * $134.97 = $539.88
She should choose Plan 1.
She will save $539.88 - $419.88 = $120

Answer:
The graph in the attached figure
Step-by-step explanation:
we have
![x-4y < 0](https://tex.z-dn.net/?f=x-4y%20%3C%200)
isolate the variable y
![-4y < -x](https://tex.z-dn.net/?f=-4y%20%3C%20-x)
Divide by -4 both sides
Remember
When you multiply or divide both sides of an inequality by a negative number, you must reverse the inequality symbol
so
![y > \frac{x}{4}](https://tex.z-dn.net/?f=y%20%3E%20%5Cfrac%7Bx%7D%7B4%7D)
The solution of the inequality is the shaded area above the dashed line ![y=\frac{x}{4}](https://tex.z-dn.net/?f=y%3D%5Cfrac%7Bx%7D%7B4%7D)
The slope of the dashed line is positive m=1/4
The y-intercept of the dashed line is (0,0)
The x-intercept of the dashed line is (0,0)
