Solve for x: −2(x + 3) = −2x − 6

patriot [66]

Answer: Option C

all real numbers

Step-by-step explanation:

We have the following equation

$-2(x + 3) =-2x - 6$

We must solve for the variable x

$-2(x + 3) =-2x - 6$

Apply the distributive property of the left side of equality

$-2*x -2*3 =-2x - 6$

$-2x -6 =-2x - 6$

Add 6 on both sides of equality

$-2x -6 +6=-2x - 6+6$

$-2x=-2x$

Divide between -2x on both sides of the equation

$\frac{-2x}{-2x}=\frac{-2x}{-2x}$

$1=1$

The variable x is eliminated. This means that equality does not depend on the value of x. In other words, equality is satisfied for any value of x. Therefore the equation has infinite solutions

The answer is all real numbers

There is a 60% chance that your math teacher will give a pop quiz tonight, and due to the fact that you have a soccer game, ther

Verizon [17]

Answer:

D) 0.51, and do the homework

Step-by-step explanation:

First, we have the event "Probability of give a pop quiz" and event 2 "Probability of not doing homework".

The soccer game, and the pop quiz are not related, which means that the outcome of one or another event, will not affect the fact of the soccer game to be realized, so these 2 previous events are independent events, you can either have the quiz and not doing the homework, or even not have the quiz but still do the homework, the result of one will not affect the outcome of the other, hence:

P(A∩B) = P(A) * P(B)

Replacing the data we have:

P(A∩B) = 0.6 * 0.85

P(A∩B) = 0.51 or 51%

This result is lower than 80%, therefore, you'll do the homework
