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 dimensions of this cube are height (h) = 4, length (l) = 8, and width (w) = 3. What is the volume?
| 96 | |
| 384 | |
| 18 | |
| 12 |
The volume of a cube is height x length x width:
v = h x l x w
v = 4 x 8 x 3
v = 96
Solve -6c + 9c = -c - 7y - 1 for c in terms of y.
| -2\(\frac{1}{4}\)y + \(\frac{1}{2}\) | |
| -\(\frac{6}{7}\)y + \(\frac{5}{14}\) | |
| 3\(\frac{1}{5}\)y + \(\frac{1}{5}\) | |
| y - 2 |
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.
-6c + 9y = -c - 7y - 1
-6c = -c - 7y - 1 - 9y
-6c + c = -7y - 1 - 9y
-5c = -16y - 1
c = \( \frac{-16y - 1}{-5} \)
c = \( \frac{-16y}{-5} \) + \( \frac{-1}{-5} \)
c = 3\(\frac{1}{5}\)y + \(\frac{1}{5}\)
