Answer:

x=13

Step-by-step explanation:

First, you add the x's together: 2x+x=3x

Now you have:3x-1=38

Add 1 to both sides: 3x=39

1 cancel on the left side of the equation

Divide 3 on both sides: x=39/3

3 cancels on the left side and 39 divided by 3 is 13:

x=13

Hope this helps!

The table represents a liner function. What is the slope of the function?

Liono4ka [1.6K]

Answer:

The slope is 3.

Step-by-step explanation:

Let's use the slope formula to calculate the slope of this function. Remember, slope equals rise over run, or the difference between y coordinates divided by the difference between x coordinates of 2 points on the graph.

Let's use the last 2 points in the table: (1, 7) and (2, 10)

$\frac{y_{2} - y_{1} }{x_{2} - x_{1} }$

= $\frac{10 - 7}{2 - 1}$

= $\frac{3}{1}$

The slope of this function is 3!

Hope this helps :) Feel free to ask me any questions!
