Solve for w. | – w|≥2 Write a compound inequality like 1 < x < 3 or like x < 1 or x > 3. Use integers, proper fracti

Eduardwww [97]

Answer:

$-2 \geq w \geq 2$

Step-by-step explanation:

Given

$|-w| \geq 2$

Required

Solve for w

$|-w| \geq 2$

In absolution functions;

$|-w| = |w|$

So, the given expression can be rewritten as

$|w| \geq 2$

Removing the absolute sign, will gibe

$w \geq 2$ or $w \leq -2$

When the second inequality os rewritten, it gives

$w \geq 2$ or $-2 \geq w$

Reorder both inequalities

$-2 \geq w$ or $w \geq 2$

Lastly, both inequalities are combined

$-2 \geq w \geq 2$

The quotient of two rational numbers is positive. What can you conclude about the signs of the dividend and the divisor? That’s

satela [25.4K]

Answer:

The divisor and dividend have the same signs.

Step-by-step explanation:

Let's look at all of the possible outcomes of dividing with different signs.

Positive / positive = positive

Positive / negative = negative

Negative / positive = negative

Negative / negative = positive

We can see that whenever the signs are the same, the quotient is positive.

1. You are rolling a pair of dice. What's the probability of getting different numbers on both dice?

GaryK [48]

Answer:

Step-by-step explanation:

Total outcomes:

6*6 = 36

Outcomes with same numbers on both dice:

Outcomes with different numbers on both dice:

36 - 6 = 30

Probability of different numbers on both dice:

30/36 = 5/6

Solve the system using elimination. 2x + 18y = -9 4x + 18y = -27

Elan Coil [88]

First, let's cancel out the x by multiplying 2x + 18y = -9 by -2.

-2 ( 2x + 18y = -9) = -4x -36y = 18

Then, we combine the two equations.

-4x + 4x = 0

18y - 36y = -18y

-27 + 18 = -9

Our new equation is -18y = -9.

Now, divide both sides by -18.

-18y / -18 = y

-9/ -18 = 1/2

y = 1/2

We can plug in a value for y since y = 1/2 now.

Let's use 2x + 18y = -9

Plug in y.

2x + 18(1/2) = -9

2x + 9 = -9

Then, subtract 9 from both sides.

2x = -18

Divide by 2.

2x/2 = x

-18/2 = -9

x = -9

Lastly, we can plug in both x and y values to see it works.

2(-9) + 18(1/2) = -9

-18 + 9 = -9

Therefore, the values of x and y does work.

x = -9

y = 1/2
