Can someone please explain why x= -2! ASAP!!

Answers

Because you add both negative x’s which is -2 and add the -6 in the right side so then it’s -2x=4
Divide and you get x=-2

9514 1404 393

Answer:

  x = -2 because that is the value that makes the equation true

Step-by-step explanation:

Minus signs are everywhere. They can all be eliminated by multiplying both sides of the equation by -1.

  -1(-x -6 -x) = -1(-2)

  (-1)(-x) +(-1)(-6) +(-1)(-x) = 2 . . . . . distribute the -1

  x + 6 + x = 2 . . . . . . . . simplify

  x + x + 6 = 2 . . . . . . . . rearrange

  (1 +1)x +6 = 2 . . . . . . . . factor, using the distributive property

  2x +6 = 2 . . . . . . . . . . . simplify

  2x +6 -6 = 2 -6 . . . . . . subtract 6 from both sides

  2x = -4 . . . . . . . . . . . . . simplify

  (2x)/2 = (-4)/2 . . . . . . . divide both sides by 2

  x = -2 . . . . . . . . . . . . . . simplify

x is -2 because that is the value we get when we apply the properties of equality to the equation. We can check to see if it works in the original equation.

Check

-x -6 -x = -2

-(-2) -6 -(-2) = -2 . . . . put -2 where x is

2 -6 +2 = -2 . . . . . . . . simplify the signs

-4 +2 = -2 . . . . . . . . . . add the first two terms (could do all at once)

-2 = -2 . . . . . . . . yes, the value of x=-2 makes the equation true

Additional comment

The properties of equality we're concerned with here are the multiplication property of equality, the addition property of equality and the division property of equality. Respectively, these tell us that multiplying, adding, or dividing both sides of the equation by the same number doesn't change the value of the variable.

These properties are essential to understanding how algebra works.

O-2 to -1
O -1.5 to 0.5
O 0 to 1
O 0.5 to 1.5

Answers

There is a negative rate of change in the function In the interval (-2,-1) on the x-axis.

What is the average rate of change between two coordinates?

The slope of the straight line connecting two points is the average rate of change between those two coordinates.

We can infer from the graph,

the slope of the straight line connecting these points is negative in the range of -2 to -1.

As a result, the function's rate of change over this interval is negative.

Hence, In the interval –2 to –1 there is a negative rate of change in the function.

Find the missing side

Answers

Answer:

Assuming you're referring to the sides of a right triangle, the missing side X would be 12.

Step-by-step explanation:

The Pythagorean Theorem states that the two legs of a right triangle squared and added together is equal to the hypotenuse squared. [tex]13^{2}[/tex] is 169, [tex]5^{2}[/tex] is 25, 169 - 25 = 144. Take the square root of 144 and you'll get 12, which is the missing side of the right triangle.

Find the length of the missing side. Simplify all radicals.

Answers

Answer:

b = 9√5 (see below)

Step-by-step explanation:

Using the Pythagorean Theorem, you can find the missing side. The two sides connect to the right angle are the legs, and the sloping side across from the right angle is the hypotenuse.

We know that:

a² + b² = c²

—where a and b are legs and c is the hypotenuse.

Plug in the known values:

a² + b² = c²

18² + b² = 27²

324 + b² = 729

b² = 405

√b² = √405

b = √81 √5

b = 9√5

Answer:

20

Step-by-step explanation:

A^2+B^2=C^2

18^2+B^2= 27^2

324+B^2= 729

-324           -324

        B^2  = 405

         B= [tex]\sqrt{405)\\[/tex]

Answer:

Step-by-step explanation:

Since this is a test/homework, I'll give you a hint.

For a linear graph, if you took a ruler, and traced the "dots", it should always be in a straight line.

Another way, is finding a pattern. I can't really explain this so much, since it's fairly basic. Just find two dots, and see if they are similar in any way. If they are, good job! Find another. If their isn't, maybe try searching for another.

The third way: You could use the equation mx+b=y, but this is just a bit ridiculous for this problem, since you could just eye it.

Hope this helps!

The test will cover 120 pages in his textbook. He has read only 36 pages. If he plans to read an equal amount every day of the week to finish the 120 pages, how much must read each day?

Answers

Answer:

He must read each day=12 pages

Step-by-step explanation:

We are given that

Total number of pages in textbook=120

He has read number of pages=36

Number of days in a week=7

We have to find the number of pages read each day to finish 120 pages in a week.

Number of pages remaining for reading=120-36

Number of pages remaining for reading=84

Now,

Number of pages read each day=[tex]\frac{84}{7}[/tex]

Number of pages read each day=12

Hence, he must read each day=12 pages

A person earns ​$17,000 one year and gets a​ 5% raise in salary. Calculate the new yearly salary using a percent greater than 100.

Answers

Answer:

$17850

Step-by-step explanation:

Adding 5% of a number to that number is the same as taking 105% of the number.

Taking 105% of a number is the same as multiplying it by 1.05

This means that 105% of 17,000 is:

17,000*1.05 = 17850
