Solve for x:
-8x + 1 > -7 - 4x
| x > 2 | |
| x > -1 | |
| x > -\(\frac{2}{9}\) | |
| x > 6 |
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.
-8x + 1 > -7 - 4x
-8x > -7 - 4x - 1
-8x + 4x > -7 - 1
-4x > -8
x > \( \frac{-8}{-4} \)
x > 2

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

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.
A coordinate grid is composed of which of the following?
origin |
|
x-axis |
|
all of these |
|
y-axis |
The coordinate grid is composed of a horizontal x-axis and a vertical y-axis. The center of the grid, where the x-axis and y-axis meet, is called the origin.
The endpoints of this line segment are at (-2, 4) and (2, 2). What is the slope of this line?
| \(\frac{1}{2}\) | |
| -2 | |
| -\(\frac{1}{2}\) | |
| 1 |
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, 4) and (2, 2) so the slope becomes:
m = \( \frac{\Delta y}{\Delta x} \) = \( \frac{(2.0) - (4.0)}{(2) - (-2)} \) = \( \frac{-2}{4} \)
