Answer:

[tex](-4, -\frac{1}{2})[/tex]

Step-by-step explanation:

Hi there!

We are given the line segment, with the end points AB

The coordinates of A are (-5, -4), and the coordinates of B are (-3, 3).

We want to find the midpoint of the line segment AB

The midpoint formula is given as [tex](\frac{x_1+ x_2}{2}, \frac{y_1 + y_2}{2})[/tex], where [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] are coordinates

We have two coordinates, which is what we need, but let's label their values to avoid any confusion:

[tex]x_1=-5\\y_1=-4\\x_2=-3\\y_2=3[/tex]

Now substitute those values into the formula:

[tex](\frac{x_1+ x_2}{2}, \frac{y_1 + y_2}{2})[/tex]

[tex](\frac{-5+ -3}{2}, \frac{-4+ 3}{2})[/tex]

Now simplify the numerator and denominator

[tex](\frac{-8}{2}, \frac{-1}{2})[/tex]

Simplify again:

The midpoint is (-4, [tex]-\frac{1}{2}[/tex])

Hope this helps!

Answer:

-13, 8

Step-by-step explanation:

(x-3)(x+8) = 80

use FOIL to eliminate parenthesis

x² +8x - 3x - 24 = 80

combine like terms

x² + 5x - 24 = 80

move the constant to the left

x² + 5x - 104 = 0

factor x and then factor -8

x(x+13) - 8(x+13) = 0    factor (x+13)

(x+13)(x-8) = 0

separate into possible cases

x + 13 = 0

x - 8 = 0

solve

x = -13

x = 8

Answer:

sorry I don't no the answer

Answer:

Step-by-step explanation:

Given,

Perimeter of fencing bought by Claire for rectangular garden

= 2(4x - 4 + x - 4)

= 2 ( 5x - 8 )

= 10x - 16

Perimeter of fencing bought by Claire for triangular garden

= (3x - 1) + (3x - 1) + 3x

= 3x + 3x + 3x - 1 - 1

= 9x - 2

Since,

The two gardens have same perimeter,

By the problem,

10x - 16 = 9x - 2

=> 10x - 9x = 16 - 2

=> x = 14

Hence,

Feet of fencing bought by her,

Putting value in any of the perimeters of the gardens,

10x - 16

= 10(14) - 16

= 140 - 16

= 124 feet (Ans)

Answer:

  3.24

Step-by-step explanation:

The weighted average GPA is ...

  (9(2.40) +18g)/(9+18) = 2.96

Then the girls' GPA (g) is ...

  ((27)(2.96)-9(2.40))/18 = g = 58.32/18 = 3.24

The GPA of the girls in the class is 3.24.

_____

Additional comment

The solution expression can be rearranged to ...

  ((9+18)(2.96) -(9)(2.40))/18 = g

  2.96 +(9/18)(2.96 -2.40) = g

  2.96 +(1/2)(0.56) = g

That is, the difference of the boys' GPA from the overall average, multiplied by the ratio of boys to girls, is the amount that must be added to the overall average to get the girls' GPA. This is arithmetic you can do in your head.

The key idea with the average is that the sum of differences from the average is zero. If 9 boys each have a GPA 0.56 units below the average, then twice as many girls will each have a GPA that is half as much above the average.

Answer:

-2.25 + 1 1/10 = -1.15

-2.25 + 1 2/10 = -1.05

-2.25 + 1 3/10 = -0.95

-2.25 + 1 4/10 = -0.85

-2.25 + 1 5/10  = -0.75

-2.25 + 1 6/10  = -0.65

-2.25 + 1 7/10  = -0.55

-2.25 + 1 8/10 = -0.45

-2.25 + 1 9/10 = -0.35

-2.25 + 1 8/9   = -0.361111111

-2.25 + 1 7/8   = -0.375

(-2.25) + 1 6/7 = -0.392857143

(-2.25) + 1 5/6 = -0.416666667

(-2.25) + 1 4/5 = -0.45

(-2.25) + 1 3/4 = -0.5

(-2.25) + 1 2/4 = -0.75   is the same as 1 5/10 = -2.25 + 1/2 = -0.75

(-2.25) + 1 2/3 = -0.583333333 - 0.47222222

(-2.25) + 1 7/9 =-0.472222222   1 7/9 is smaller number than 1 2/3 by 0.10555555

We know 1  7/9 it is smaller than 1 8/9 as  -2.25 + 1 8/9   = -0.361111111 but only by -0.111111112

as the difference of 1/9 = -0.111111112

etc etc.

Summary when adding additional 1/10 it adds 0.1

when adding additional 1/9 it adds 0.111111112

when adding additional 1/8 it adds 0.125

when adding additional 1/7 it adds 0.142857143

when adding additional 1/6 it adds 0.166666667

when adding additional 1/5 it adds 0.2

when adding additional 1/4 it adds 0.25

when adding additional 1/3 it adds 0.333332224

when adding additional 1/2 it adds 0.5

when adding additional 10/2 it adds 5 etc etc.

The 26.66 servings you can, make per 5 lb bag if  recipe for burritos requires 3 ounces of vegan cheese per serving.

It is defined as the conversion from one quantity unit to another quantity unit followed by the process of division, multiplication by a conversion factor.

We have:

You buy vegan shredded cheese in 5 lb bags.

1 lb = 16 ounces

5 lb = 80 ounces

Recipe for burritos requires 3 ounces of vegan cheese per serving.

1 → 3

x → 80

x is the number of serving

x = 80/3 = 26.66

Thus, the 26.66 servings you can, make per 5 lb bag if  recipe for burritos requires 3 ounces of vegan cheese per serving.

Answer:

They lost 29.3% of the softball games.

Step-by-step explanation:

Total number of games = 75

Number of games won = 55

Number of games lost = 75 − 55 = 22

Percentage of games lost: Number of games lost/ total games x 100%

Which means: 22/75 x 100% = 29.3%

Answer:

Step-by-step explanation:

Length, L = 2x + 2

Width, W = 3x

Height, H = 4x - 2

[tex]Surface\ Area = 2 (LW + WH + HL)\\\\[/tex]

                     [tex]= 2 ( (2x +2)(3x) + (3x)(4x -2) + (4x - 2)(2x + 2))\\\\=2(6x ^2 + 6x + 12x^2 - 6x + 8x^2 + 8x - 4x - 4)\\\\=2(26x^2 +4x -4) \ square \ units[/tex]

Step-by-step explanation:

[tex]\angle{1} = 77°[/tex] because they are vertical angles.

The 77°-angle is supplementary with [tex]\angle{2}[/tex] therefore

[tex]77° + \angle{2} = 180° \Rightarrow \angle{2} =180° -77° = 103°[/tex]

[tex]\angle{3}[/tex] and [tex]\angle{2}[/tex] are vertical angles so

[tex]\angle{3} = \angle{2} = 103°[/tex]

Answer:

103 = angle 3

103 = angle 2

angle 1 = 77

Step-by-step explanation:

angle 1 = 77

angle 2 = angle 3

360 - 77x2 = 206

206/2 = 103

Step-by-step explanation:

3y+8y=11y and -ax+4x=4ax

Answer:

a = 6

Step-by-step explanation:

Perpendicular lines have slope that are negative reciprocal of each other. There product = -1

Solve both equations for y.

3y - ax = 8                                 4x + 8y = 2

3y = ax + 8                                  8y = -4x + 2

y = ax/3 + 8/3                               y = -4x/8 + 2/8

 y = a/3(x) + 8/3                              y = -1/2(x) + 1/4

Now you know that the slope of  y = -1/2(x)+ 1/4  is -1/2

and the slope of y = a/3(x) + 8/3 is a/3.  

Looking for the value of "a" that will make the lines perpendicular.

You know that one line slope is -1/2 so the other line slope is 2 because the slope are negative reciprocal.   Also remember that the slope is the coefficient of the x term.

Now   a/3 = 2 ; a = 6

Using a system of equation, the Number of tickets sold at $27 is - 380615

Let :

a + b = 6000 - - - - (1)

27a + 40b = 5188000 - - - - - (2)

From (1) :

Put (3) in (2)

27a + 40(6000 - a) = 5188000

27a + 240000 - 40a = 5188000

-13a = 5188000 - 240000

-13a = 4948000
