2 + 6x = 1 - X<br> Please help
Fynjy0 [20]

Answer:

-1/7

Step-by-step explanation:

The first step is to isolate the variable, x. To do so, add x to both sides. This gives you the new equation: 2 + 7x = 1.

Now, subtract 2 from both sides to further isolate the variable, giving you 7x = -1.

Divide both sides by 7, giving you the final equation of x = -1/7.

For each ordered pair in the table, how does the second number compare to the first number... can yall tell me I need to turn it
spayn [35]

Answer:

The first number in each ordered pair tells how far across the X line is to move. The second number in each ordered pair tells how far up or down the Y line is to move. The point where the X and Y lines cross is marked “0” on the graph. It is called the “origin,” and is the starting point for plotting points.
