Find the slope between these two points: (3, -10) and (-2, -30). Show all of your work. what the answer

Harlamova29_29 [7]

$\huge\text{$m=\boxed{4}$}$

Hey there! Start with the slope formula, where $(x_1,y_1)$ and $(x_2,y_2)$ are the two known points.

$\begin{aligned}m&=\dfrac{y_2-y_1}{x_2-x_1}\\&=\frac{-30-(-10)}{-2-3}\end{aligned}$

Simplify.

$\begin{array}{c|l}\textbf{Solving}&\textbf{Reason}\\\cline{1-2}\\m=\dfrac{-30+10}{-2-3}&x-(-y)=x+y\\\\m=\dfrac{-20}{-5}&\text{Addition and subtraction}\\\\m=\dfrac{20}{5}&\text{The negatives cancel out}\\\\m=\dfrac{4}{1}&\text{Divide the numerator and denominator by $5$}\\\\m=\boxed{4}&\dfrac{x}{1}=x\end{aligned}$

Which of the following is an equivalent form of the compound inequality<img src="https://tex.z-dn.net/?f=%20%20-%2044%20%5C%20%2

Novay_Z [31]

Given the compound inequality:

$-44>-2x-8⩾-8$

Let's find the equivalent form of the inequality.

To find the equivalent form, let's simplify the inequality.

SInce it is a compund inequality, we are to seperate the inequalities.

Simplify the first two inequalities, then simplify the last two inequalities.

We have:

First two inequalities: -44 > -2x - 8

Last two inequalities: -2x - 8 ⩾ -8

Let's simplify both

$\begin{gathered} -44>-2x-8 \\ \\ Rewrite\text{ the inequality and change the inequality sign:} \\ -2x-8$ $\begin{gathered} \text{Second inequality:} \\ -2x-8⩾-8 \\ \end{gathered}$

Therefore, the equivalent form is:
