If the length of AB equals the length of BD, point B __________ this line segment.
intersects |
|
bisects |
|
midpoints |
|
trisects |
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.
Solve for b:
-2b + 0 = -1 + b
| 4\(\frac{1}{2}\) | |
| \(\frac{6}{7}\) | |
| \(\frac{1}{3}\) | |
| -1\(\frac{4}{5}\) |
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 equal sign and the answer on the other.
-2b + 0 = -1 + b
-2b = -1 + b + 0
-2b - b = -1 + 0
-3b = -1
b = \( \frac{-1}{-3} \)
b = \(\frac{1}{3}\)
The endpoints of this line segment are at (-2, 4) and (2, -6). What is the slope of this line?
| 1 | |
| -3 | |
| 3 | |
| -2\(\frac{1}{2}\) |
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, -6) so the slope becomes:
m = \( \frac{\Delta y}{\Delta x} \) = \( \frac{(-6.0) - (4.0)}{(2) - (-2)} \) = \( \frac{-10}{4} \)A quadrilateral is a shape with __________ sides.

A quadrilateral is a shape with four sides. The perimeter of a quadrilateral is the sum of the lengths of its four sides.
Solve -3c + 2c = 7c - 7x + 6 for c in terms of x.
| \(\frac{9}{10}\)x - \(\frac{3}{5}\) | |
| -\(\frac{1}{5}\)x - \(\frac{4}{5}\) | |
| -4x + 3 | |
| \(\frac{3}{5}\)x - \(\frac{3}{5}\) |
To solve this equation, isolate the variable for which you are solving (c) on one side of the equation and put everything else on the other side.
-3c + 2x = 7c - 7x + 6
-3c = 7c - 7x + 6 - 2x
-3c - 7c = -7x + 6 - 2x
-10c = -9x + 6
c = \( \frac{-9x + 6}{-10} \)
c = \( \frac{-9x}{-10} \) + \( \frac{6}{-10} \)
c = \(\frac{9}{10}\)x - \(\frac{3}{5}\)
