A trapezoid is a quadrilateral with one set of __________ sides.
equal length |
|
equal angle |
|
parallel |
|
right angle |
A trapezoid is a quadrilateral with one set of parallel sides.
Solve for x:
-5x + 7 < \( \frac{x}{1} \)
| x < 3\(\frac{3}{17}\) | |
| x < 2\(\frac{4}{5}\) | |
| x < 1\(\frac{1}{6}\) | |
| x < \(\frac{8}{13}\) |
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.
-5x + 7 < \( \frac{x}{1} \)
1 x (-5x + 7) < x
(1 x -5x) + (1 x 7) < x
-5x + 7 < x
-5x + 7 - x < 0
-5x - x < -7
-6x < -7
x < \( \frac{-7}{-6} \)
x < 1\(\frac{1}{6}\)
A coordinate grid is composed of which of the following?
origin |
|
y-axis |
|
all of these |
|
x-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, 2) and (2, 0). What is the slope-intercept equation for this line?
| y = -\(\frac{1}{2}\)x + 1 | |
| y = -x + 3 | |
| y = -x - 1 | |
| y = -3x - 1 |
The slope-intercept equation for a line is y = mx + b where m is the slope and b is the y-intercept of the line. From the graph, you can see that the y-intercept (the y-value from the point where the line crosses the y-axis) is 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, 2) and (2, 0) so the slope becomes:
m = \( \frac{\Delta y}{\Delta x} \) = \( \frac{(0.0) - (2.0)}{(2) - (-2)} \) = \( \frac{-2}{4} \)Plugging these values into the slope-intercept equation:
y = -\(\frac{1}{2}\)x + 1
To multiply binomials, use the FOIL method. Which of the following is not a part of the FOIL method?
First |
|
Inside |
|
Odd |
