Answer:

5x + 4y - 20 = 0

Step-by-step explanation:

1. Find the two points given: (0,5) and (4,0)

2. Find the slope of the line:

      m = [tex]\frac{5-0}{0-4} = \frac{-5}{4}[/tex]

3. Find y intercept by plugging in one point into the y-intercept form

      y = (-5/4) x + b

      0 = (-5/4) (4) + b

      b = 5

4. Write out the equation in y-intercept form

      y = (-5/4) x + 5

5. Rewrite it in Ax + By + C = 0 form

        (5/4) x + y - 5 = 0

6. Since A B C all need to be integers, multiply the whole equation by 4

       5x + 4y - 20 = 0

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:

[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:

Step-by-step explanation:

Answer:

x ≥ - 2

Step-by-step explanation:

3x + 10 ≥ 4 ( subtract 10 from both sides )

3x ≥ - 6 ( divide both sides by 3 )

x ≥ - 2

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!

Answer:

x(Gail)=8 and y(Helen)=18

Step-by-step explanation:

2x+2=y and x+10=y

Plug y in and solve for x

2x+2=(x+10)

2x-x=10-2

x=8

Plug x in and solve for y

(8)+10=y

y=18

Answer:

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.

You can think of it as A x B = B x A

Answer:

x=length

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:

Step-by-step explanation:

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
