Answer: y=|3(x+2)| = |3x+6|

You may want to verify that the points shown on the graphs indeed satisfy the above equation:

(-3,3): 3=|3(-3)+6|=3 (True)

(-2,0): 0=|3(-2)+6|=0 (True)

(-1,3): 3=|3(-1)+6|=3 (True)

This confirms the equation above is correct.

Answer:

Step-by-step explanation:

11) First write in decreasing exponential terms and fill in blanks with zeros.

Our goal is to eliminate all term in the dividend by subtraction

________________

2v - 2 | 2v³ - 16v² + 0v + 13

we see that 2v needs to be multiplied by 1v² to eliminate the first term

v²

2v - 2 | 2v³ - 16v² + 0v + 13

- (2v³ - 2v²)

0 - 14v²

multiply your estimate by your divisor and subtract from the dividend.

bring down the next term and repeat.

v² -7v

2v - 2 | 2v³ - 16v² + 0v + 13

- (2v³ - 2v²)

0 - 14v² + 0v

-(-14v² + 14v)

- 14v

repeat again

v² - 7v - 7

2v - 2 | 2v³ - 16v² + 0v + 13

- (2v³ - 2v²)

0 - 14v² + 0v

-(-14v² + 14v)

- 14v + 13

-(-14v + 14)

-1

and remainder gets put over the divisor and appended

v² - 7v - 7 - 1/(2v - 2)

13) Same process

5a + 1 | 40a³ - 12a² - 39a - 5

8a²

5a + 1 | 40a³ - 12a² - 39a - 5

-(40a³ + 8a²)

-20a² - 39a

8a² - 4a

5a + 1 | 40a³ - 12a² - 39a - 5

-(40a³ + 8a²)

-20a² - 39a

-(-20a² - 4a)

-35a - 5

8a² - 4a - 7

5a + 1 | 40a³ - 12a² - 39a - 5

-(40a³ + 8a²)

-20a² - 39a

-(20a² - 4a)

-35a - 5

-(-35a - 7)

8a² - 4a - 7 + 2/(5a + 1)

What is the answer to the questions

loris [4]

<h3>Answer: x = 40</h3>

===================================================

Work Shown:

A+B+C = 180 ..... three angles of any triangle add to 180

(2x+10)+(x)+(2x-30) = 180

5x-20 = 180

5x = 180+20 .... adding 20 to both sides

5x = 200

x = 200/5 ... dividing both sides by 5

x = 40

This is the measure of angle B

We can stop here.

If you need to know the values of the other angles, then,

angle A = 2x+10 = 2*40+10 = 90
angle C = 2x-30 = 2*40-30 = 50

Then note how A+B+C = 90+40+50 = 90+90 = 180 which helps confirm our answer.
