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:

-2x-8

ANSWER:

d.\text{   -2x - 8

Find the value of b.
Trava [24]

Answer: \Large\boxed{b=145^\circ}

Step-by-step explanation:

<u>Given information</u>

∡1 = 35°

∡b = ?

Total Angle = 180° (Supplementary Angle)

<u>Derived formula from the given information</u>

∡1 + ∡b = Total Angle

<u>Substitute values into the given formula</u>

(35) + b = 180

<u>Subtract 35 on both sides</u>

35 + b - 35 = 180 - 35

\Large\boxed{b=145^\circ}

Hope this helps!! :)
