Answer:

C. x ≥ -4

Step-by-step explanation:

To solve this inequality isolate the variable. Do this by using the properties of equality, specifically the division property. So, divide both sides by -10. This equals, x ≤ -4. However, whenever an inequality is divided or multiplied by a negative number the sign must be flipped. Therefore, the final answer is x ≥ -4.

Solve the following inequality for w then simplify <br> -w+9&gt;6w+8
Alla [95]

Answer:

\displaystyle (-\infty,\frac{1}{7})

Step-by-step explanation:

<u>Inequalities</u>

To solve the inequality:

-w+9>6w+8

We need to perform the required operations on both sides of the inequality to have the variable w isolated.

First, we subtract 9:

-w+9>6w+8

-w>6w+8-9

Subtracting 6w:

-w-6w>+8-9

Operating:

-7w>-1

Now we divide by -7 but recall that when dividing by a negative number, we must flip the inequality sign:

\displaystyle w

Operating:

\displaystyle w

Solution:

\mathbf{\displaystyle (-\infty,\frac{1}{7})}
