Solve for x:
-2x + 8 < -4 + 8x

54% Answer Correctly

	x < -\(\frac{1}{6}\)
	x < \(\frac{3}{4}\)
	x < -3
	x < 1\(\frac{1}{5}\)

Solution

To solve this equation, repeatedly do the same thing to both sides of the equation until the variable is isolated on one side of the < sign and the answer on the other.

-2x + 8 < -4 + 8x
-2x < -4 + 8x - 8
-2x - 8x < -4 - 8
-10x < -12
x < \( \frac{-12}{-10} \)
x < 1\(\frac{1}{5}\)

To multiply binomials, use the FOIL method. Which of the following is not a part of the FOIL method?

83% Answer Correctly

	First
	Inside
	Odd
	Last

Solution

To multiply binomials, use the FOIL method. FOIL stands for First, Outside, Inside, Last and refers to the position of each term in the parentheses.

The endpoints of this line segment are at (-2, 6) and (2, -4). What is the slope of this line?

46% Answer Correctly

	-2\(\frac{1}{2}\)
	-\(\frac{1}{2}\)
	1\(\frac{1}{2}\)
	2

Solution

The slope of this line is the change in y divided by the change in x. The endpoints of this line segment are at (-2, 6) and (2, -4) so the slope becomes:

m = \( \frac{\Delta y}{\Delta x} \) = \( \frac{(-4.0) - (6.0)}{(2) - (-2)} \) = \( \frac{-10}{4} \)
m = -2\(\frac{1}{2}\)

If AD = 16 and BD = 6, AB = ?

75% Answer Correctly

	17
	9
	10
	13

Solution

The entire length of this line is represented by AD which is AB + BD:

AD = AB + BD

Solving for AB:

AB = AD - BD
AB = 16 - 6
AB = 10

If the length of AB equals the length of BD, point B __________ this line segment.

45% Answer Correctly

	intersects
	midpoints
	bisects
	trisects

Solution

A line segment is a portion of a line with a measurable length. The midpoint of a line segment is the point exactly halfway between the endpoints. The midpoint bisects (cuts in half) the line segment.
