Answer:

y = -3x + 22

Step-by-step explanation:

To find m, find the change in y and divide it by the change in x.

For example, the change in y between 19 and 13 is -6. Then determine the change in x. For example, since we determined the change in 19 and 13, let's look at the change in the x coordinates that pair with 19 and 13: 1 and 3. The change in x between 1 and 3 is 2. Now divide the change in y by the change in x: -6/2 = -3. So now we have the equation y = -3x + b, but we still need to figure out b, or the y-intercept. To do this, we need to figure out a pattern in the table to find out what y is equal to when x = 0, the definition of a y-intercept. From just the table alone, it looks like for every 2 units the x-coordinate decreases, the y-coordinates increases by 6. We could also just as easily say that for every 1 unit the x-coordinate decreases, the y-coordinate increases by 3. From this definition, if we look at the coordinate (1, 19), if we were to decrease 1 from the x-coordinate, we would have to increase the y-coordinate by 3 which we can write as (x - 1, y + 3). So, we would get (0, 22). So, when x = 0, y = 22.

Answer:

[tex]\sqrt[10]{77}[/tex]

Step-by-step explanation:

[tex]77^\frac{1}{10}[/tex] is the same as [tex]\sqrt[10]{77^1} ,[/tex] or simply [tex]\sqrt[10]{77}[/tex]

77^1/10 can be written as [tex]\sqrt[10]{77}[/tex]

The principal nth root of a is written as n√a , where n is a positive integer greater than or equal to 2. In the radical expression, n is called the index of the radical.

A radical symbol √ is used to represent a square root; the number or expression included within the radical symbol, designated by the letter a below, is known as the radicand.

We have that [tex]77 ^ {1/10}[/tex].

Now, if we have given that √4 we can write it as [tex]\sqrt[2]{4}[/tex]

Again, if we have [tex]7^{1/3}[/tex] we can write it as [tex]\sqrt[3]{7}[/tex]

Similarly we can write 77^1/10 as  [tex]\sqrt[10]{77}[/tex]

Answer:

136 degrees

Step-by-step explanation:

136 degrees + 44 degrees = 180 degrees

Answer:

x = 136 degrees

Step-by-step explanation:

180 - 44 = 136

Both angles are supplementary

Answer:

x = 145, y = 35

Step-by-step explanation:

so y is equal to 35 because alternate interior angles are equal to each other (you can search this up if you're confused) and x = 145 because of supplementary angles so I did 180 - 35 = 145. hope this helps!

The equation 4 ∙ 5 = 5 ∙ 4 demonstrates the Commutative property of multiplication.

Step-by-step explanation:

Commutative property is A × B = B × A

So the equation  4 ∙ 5 = 5 ∙ 4 is same as commutative property

Answer:

The equation 4 ∙ 5 = 5 ∙ 4 demonstrates the commutative property of multiplication.

Step-by-step explanation:

The commutative property means that the positions of the numbers on each side of the equation can be swapped and both sides would be equal.

x-12=width

you techinally have to count 2 lengths and 2 widths.

2x + 2x - 24= 64

4x = 88

x = 22

so the length is 22 and the width is 10

Answer: x = -5

-------------------------------------------------------------------------------------------------------------

Step-by-step explanation:

Let's solve your equation step-by-step.

−5(1−5x)+5(−8x−2)=−4x−8x                                                                                                                          

-------------------------------------------------------------------------------------------------------------

Step 1: Simplify both sides of the equation.

−5(1−5x)+5(−8x−2)=−4x−8x

(−5)(1)+(−5)(−5x)+(5)(−8x)+(5)(−2)=−4x+−8x(Distribute)

−5+25x+−40x+−10=−4x+−8x

(25x+−40x)+(−5+−10)=(−4x+−8x)(Combine Like Terms)

−15x+−15=−12x

−15x−15=−12x

-------------------------------------------------------------------------------------------------------------

Step 2: Add 12x to both sides.

−15x−15+12x=−12x+12x

−3x−15=0

-------------------------------------------------------------------------------------------------------------

Step 3: Add 15 to both sides.

−3x−15+15=0+15

−3x=15

-------------------------------------------------------------------------------------------------------------

Step 4: Divide both sides by -3.

−3x /−3  = 15/ −3

x=−5

-------------------------------------------------------------------------------------------------------------

Answer:

x=−5
