Answer:
C) 
Step-by-step explanation:
The equation of a straight line is given by:
y = mx + b
where m is the slope of the line, b is the y intercept (value of x when y is 0) and y, x are variables.
The equation of a line passing through two points (x₁, y₁) and (x₂, y₂) is given by:
From the graph, the line passes through (0, 0) and (10, -2), hence the equation of the line is:
factor out an 3x^2
3x^2(x^2 -2x+4)
The inside is not factorable
Answer:
8 ft
Step-by-step explanation:
Use pythagorean theorem. 
. Put 10 and 6 into the equation as b and c.
Therefore, the answer is 8ft.
A diagram is attached. Sorry it's kinda messy.
Answer:
15
Step-by-step explanation:
So angle 2 and angle 4 have a relationship that is called same-side interior or consecutive interior angles. The name there depends what class you are in but they mean the same thing.
If you have the transversal goes through parallel lines, then same-side interior angles will add up to 180 degrees.
So you are trying to solve the following equation for x:
angle2+angle4=180
2x+10+4x+80=180
Combine like terms:
6x+90=180
Subtract 90 on both sides:
6x =90
Divide both sides by 6:
x =90/6
Simplify:
x =15
15 is x so that the lines are parallel
