Answer:

Step-by-step explanation:

Given points A ( 1 , - 2) and B ( 5 , 4)

Mid point of AB is

= (  ( x1 +x2)/ 2     ,    ( y1+ y2)/ 2  )

= (  ( 1 + 5)/2        , ( - 2 + 4)/2  )

= ( 3 , 1 )

Answer:

x=−2

y=7

Step-by-step explanation:

5x+2y=4

x−3y=−23

In order to solve by elimination, coefficients of one of the variables must be the same in both equations so that the variable will cancel out when one equation is subtracted from the other.

5x+2y=4,x−3y=−23

To make 5x and x equal, multiply all terms on each side of the first equation by 1 and all terms on each side of the second by 5.

5x+2y=4,5x+5(−3)y=5(−23)

Simplify.

5x+2y=4,5x−15y=−115

Subtract 5x−15y=−115 from 5x+2y=4 by subtracting like terms on each side of the equal sign.

5x−5x+2y+15y=4+115

Add 5x to −5x. Terms 5x and −5x cancel out, leaving an equation with only one variable that can be solved.

2y+15y=4+115

Add 2y to 15y.

17y=4+115

Add 4 to 115.

17y=119

Divide both sides by 17.

y=7

Substitute 7 for y in x−3y=−23. Because the resulting equation contains only one variable, you can solve for x directly.

x−3×7=−23

Multiply −3 times 7.

x−21=−23

Add 21 to both sides of the equation.

x=−2

The system is now solved.

x=−2,y=7

Answer:

n = 19/18

Step-by-step explanation:

11/6 = n + 7/9

-n + 11/6 = 7/9

-n = 7/9 - 11/6

-n = -19/18

n = 19/18

Answer:

n = 19/18

Step-by-step explanation:

The equation 11/6=n+7/9 has fractions with two different denominators (6 and 9).  The LCD is 18, which is the smallest number evenly divisible by 6 and 9.  Thus, we can rewrite 11/6=n+7/9 as:

33/18 = (18/18)n + 14/18 (Now all three denominators are the same:  18)

Then 33 = 18n + 14, or

         19 = 18n

Dividing both sides by 18, we get n = 19/18

Check:  Is 11/6 = 19/18 + 7/9 true?  YES

Answer:

1. [tex]y=\frac{2}{3}x-2[/tex]

2. [tex]y=\frac{-5}{4}x+5[/tex]

Step-by-step explanation:

all you are doing is solving for "y"

Answer:

ans 1. -2x = -6-3y

-2x = 9y

xy = -2/9

ans 2. 5x = 20 - 4y

5x = 16y

xy = 5/16

Answer:

(0, -6)

Step-by-step explanation:

At the y-intercept, the x-coordinate equals zero.

3x - 4y = 24

3(0) - 4y = 24

-4y = 24

y = -6

Answer: (0, -6)

Answer:

$8,000

Step-by-step explanation:

40x20= .1s

8000=s

First option, the salesperson will earn 40*20=800 dollars.

For second option, the person will earn the amount he sells/10.

For them to be equal the second salesperson have to sell 800*10=8000 dollars of items to earn that as much money as the first salesperson.

Answer:

it is 86

Step-by-step explanation:

House 1 has 6 sticks. House 2 has 11, house 3 has 16, and the pattern goes on. Each following house uses 5 more sticks. At design 17, we can use this pattern to solve for it. We would do 5*17, remembering to add 1 as house 1 has its own additional stick. 5*17 + 1 = 86

Hope this helps, let me know if you have any questions :))

Answer:

Step-by-step explanation:

B = 35      {Alternate interior angles}

C = 75      {Corresponding angles}

D + 75 =  180 {Linear pair}

     D = 180 - 75

     D = 105

A = C   {Corresponding angles}

A = 75

E = A   {Alternate interior angles}

E = 75

Answer:

Step-by-step explanation:

Write the prime factors making up the two expressions

48x^2: 2 * 2  * 2 * 2 * 3 * x * x

32x^3:  2 * 2 * 2 * 2 * 2 * x * x * x

Underline what is common to both

The highest common factor is 2 * 2 * 2 * 2 * x  * x

The highest common factor is 16x^2

This may look very simplistic, but try a question like this

5397691 and 3271021

The method I've shown you is likely the only way you could factor these two monsters and they are relatively small numbers.
