A coordinate grid is composed of which of the following?
all of these |
|

x-axis |
|
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.
Solve -c - 3c = 6c + 7y + 2 for c in terms of y.
| -\(\frac{1}{2}\)y - \(\frac{1}{6}\) | |
| -\(\frac{1}{6}\)y - \(\frac{5}{12}\) | |
| -1\(\frac{3}{7}\)y - \(\frac{2}{7}\) | |
| -5\(\frac{2}{3}\)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.
-c - 3y = 6c + 7y + 2
-c = 6c + 7y + 2 + 3y
-c - 6c = 7y + 2 + 3y
-7c = 10y + 2
c = \( \frac{10y + 2}{-7} \)
c = \( \frac{10y}{-7} \) + \( \frac{2}{-7} \)
c = -1\(\frac{3}{7}\)y - \(\frac{2}{7}\)
