<h2>Answer:     </h2>

<u>Number lines</u>                            <u> Inequality</u>

First                   ⇔              \dfrac{x}{4}\leq\dfrac{-3}{2}

Second             ⇔              \dfrac{-75x}{4}>\dfrac{225}{2}

Third                 ⇔              \dfrac{2x}{3}>\dfrac{-16}{3}

Fourth              ⇔              \dfrac{7x}{9}>\dfrac{-14}{3}

<h2>Step-by-step explanation:</h2>

Inequality 1. \dfrac{7x}{9}>\dfrac{-14}{3}

Multiply both sides by 9 , we get

7x>-42

Divide both sides by 7, we get

x>-6 which is shown by the fourth number line.

Inequality 2. \dfrac{-75x}{4}>\dfrac{225}{2}

Multiply both sides by 4 , we get

-75x>450

Divide both sides by -6, we get

x which is shown by the second number line.

Inequality 3. \dfrac{x}{4}\leq\dfrac{-3}{2}

Multiply both sides by 4 , we get

x\leq-6 which is shown by the first number line.

Inequality 2. \dfrac{2x}{3}>\dfrac{-16}{3}

Multiply both sides by 3 , we get

2x>-16

Divide both sides by 2, we get

x>8 which is shown by the third number line.

What 2 numbers add to -3 and multiply to 2
serg [7]
We need to look at factors of 2, which are only 2 and 1... How do we get them to add to -3? Well, they have to be negative.

-2 + -1 = -3

What about the multiplication? A negative × a negative = a positive, so

-2 × -1 = 2

So your answer is

-2 and -1

Line CD passes through points (0, 2) and (4, 6). Which equation represents line CD?
Vikentia [17]
(0,2)(4,6)
slope = (6 - 2) / (4 - 0) = 4/4 = 1

y = mx + b
slope(m) = 1
use either of ur points (0,2)...x = 0 and y = 2
sub and find b, the y int
2 = 1(0) + b
2 = b

ur equation is : y = x + 2 <==
