1. Solve the inequality.

Sauron [17]

Answer:

Your final answer is either

x≥-2 if your initial inequality was

6x+2≤2(5-x)

OR

x≤-2

if your initial inequality was

6x+2≥2(x-2)

Step-by-step explanation:

As shown you have an equality, not an inequality.

-6x+2=2(5-x) distribute through parenthesis

-6x+2=2(5)+2(-x)

-6x+2=10-2x add 2x to both sides

2x-6x+2=10-2x+2x

-4x+2=10 subtract 2 from both sides

-4x+2-2=10-2

-4x=8 divide both sides by -4

-4x/(-4) = 8/(-4)

x = -2

With the ≥ or ≤ sign you would solve the exact same way

except for the point where when dividing both sides by

-4 requires you to reverse the inequality.

Your final answer is either

x≥-2 if your initial inequality was

6x+2≤2(5-x)

OR

x≤-2

if your initial inequality was

6x+2≥2(x-2)

For babysitting, Angie charges a flat fee of $3, plus $5 per hour. Write an equation for the cost, C, after h hours of babysitti

Ghella [55]

Answer:

C=5h+3 when h=5

C=28

Step-by-step explanation:

She charges $5 per hour (5h)

and a flat fee of $3 (+3).

Replace the h (the number of hours babysitting) with 5 (the amount of hours you want to find for).

Then you multiple 5 and 5, then add 3.

Which gives you an answer of $28.

Hope this helped!

Answer:

The answer to your question is x ≠ -10 x ≠ 2 x ≠ -2

Solution $\frac{(x- 8)(x + 2)}{(x + 8)(x - 2)}$

Step-by-step explanation:

Process

1.- Factor all the polynomials

$\frac{x^{2} -3x - 40}{x^{2} + 8x - 20} / \frac{x^{2}+ 13x + 40}{x^{2}+ 12x + 20}$ = $\frac{(x-8)(x + 5)}{(x + 10)(x- 2)} / \frac{(x+ 8)(x + 5)}{(x + 10)(x + 2)}$

2.- Invert the second term

= $\frac{(x- 8)(x + 5)}{(x +10)(x - 2)} \frac{(x+ 10)(x + 2)}{(x + 8)(x +5)}$

3.- Simplify

= $\frac{(x- 8)(x + 2)}{(x + 8)(x - 2)}$

4.- x must be different to

x ≠ -10 x ≠ 2 x ≠ -2

This values are from the factor expressions and then equal to zero.
