Answer:

14+6x=13, or further 1+6x=0

Step-by-step explanation:

2+3(2x+4)=13,

Distribute the 3 into the parenthesis:

2+6x+12=13

Now combine like terms: 14+6x=13.

You can also write this as 1+6x=0 by subtracting 13 to the left, though it might not be necessary.

What is the rate of change of the linear relationship modeled in the table (-2,5) (-1,4) (0,3) (1,2)

poizon [28]

The rate of change of the linear relationship is -1.

Explanation:

It is given that there is a linear relationship between all these points, these points lie on a straight line.

The equation to find the slope passing through two points $\left(x_{1}, y_{1}\right)$ and $\left(x_{2}, y_{2}\right)$ is given by

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

Substituting the points $(-2,5)$ and $(-1,4)$ , we get,

$\begin{aligned}m &=\frac{4-5}{-1+2} \\&=\frac{-1}{1} \\&=-1\end{aligned}$

Thus, the slope is -1.

Thus, the rate of change of the linear relationship is -1.
