You would take out a 4x out of both terms because this is a common factor
4x^3-36x
4x(x^2-9)
and then you would notice that (x^2-9) is a difference of squares, so that factors out too
4x(x-3)(x+3)
that is all you can factor! hope this helps
Ans: The equation that represents a proportional relationship, or a line, is y=kx, where k is the constant of proportionality. Use k=yx from either a table or a graph to find k and create the equation. Proportional relationships can be represented by tables, graphs and equations.
When grades are expressed as a quantity of 1, such as two feet per second or 5 miles per hour, they are called unit rates.
Answer:
x = (180 - 68) / 2
Step-by-step explanation:
x = 56°
Answer:

Step-by-step explanation:
The y-intercept is where x is 0 (0,y)
The x-intercept is where y is 0 (x,0)
Insert 0 as the value for x to find the corresponding y value:

Simplify multiplication:

Isolate the variable. Divide both sides by 4:

Make the variable positive. Multiply both sides by -1:

The y-intercept is at
.
Insert 0 as the value for y to determine the value of x:

Simplify multiplication:

Isolate x. Divide both sides by 5:

Multiply both sides by -1:

The x-intercept is at
.
