Answer:

Perimeter of ∆ABR = [tex] 12 + 2\sqrt{61} [/tex]

Step-by-step explanation:

Given, A(-2, -1), B(10, -1), and R(4, 4).

Perimeter of ∆ABR = [tex] \overline{AB} + \overline{BR} + \overline{AR} [/tex]

Distance between A(-2, -1) and B(10, -1) using distance formula:

[tex] \overline{AB} = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} = \sqrt{(10 -(-2))^2 + (-1 -(-1))^2} [/tex]

[tex] \overline{AB} = \sqrt{(12)^2 + (0)^2} [/tex]

[tex] \overline{AB} = \sqrt{(144 + 0)} [/tex]

[tex] \overline{AB} = \sqrt{144} = 12 [/tex]

Distance between B(10, -1) and R(4, 4):

[tex] \overline{BR} = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} = \sqrt{(4 - 10)^2 + (4 -(-1))^2} [/tex]

[tex] \overline{BR} = \sqrt{(-6)^2 + (5)^2} [/tex]

[tex] \overline{BR} = \sqrt{(36 + 25)} [/tex]

[tex] \overline{BR} = \sqrt{61} [/tex]

Distance between A(-2, -1) and R(4, 4):

[tex] \overline{AR} = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} = \sqrt{(4 -(-2))^2 + (4 -(-1))^2} [/tex]

[tex] \overline{AR} = \sqrt{(6)^2 + (5)^2} [/tex]

[tex] \overline{AR} = \sqrt{(36 + 25)} [/tex]

[tex] \overline{AR} = \sqrt{61} [/tex]

Perimeter of ∆ABR = [tex] \overline{AB} + \overline{BR} + \overline{AR} [/tex]

Perimeter of ∆ABR = [tex] 12 + \sqrt{61} + \sqrt{61} [/tex]

Perimeter of ∆ABR = [tex] 12 + 2\sqrt{61} [/tex]

Answer: It would be -8.

Step-by-step explanation: -4 = x so -4 squared is -16 times 1/2 which is -8.

Answer:

x=47 degrees

Step-by-step explanation:

X equals 47 degrees because it is congruent to the other angle that is marked. This is because of Alternate Interior Angles.

We know AD and BC are parallel because the shape is a parallelogram, this means that the other line is a transversal. When you have a transversal going through two parallel lines there are certain rules, including Alternate Interior Angles, which are two angles on opposite sides of the transversal but both on the inside of the parallel lines.

Answer:

I believe it is 14.

Step-by-step explanation:

Answer: The value of x is 14°

Step-by-step explanation:

Since line m is parallel to n, then then the two given angles will have the same measures. Meaning that 136 degrees has to equation (9x+10).

Set them to equal each other and solve for x.

9x + 10 = 136

    - 10      -10

  9x  = 126

x=  14

Answer:

1.8(3.35)=6.03

Step-by-step explanation:

Half the perimeter is equal to the length plus the width.

326 /2 = 163

Length + width = 163

87 + width = 163

Width = 163 - 87

Width = 76 meters

The answer is obviously D.

Answer:

Smallest angle = 40

Step-by-step explanation:

Angle sum property:Sum of all three angles of triangle is 180

2x - 6 + 3x + 5 + 2x + 20 = 180   {Combine like terms}

2x + 3x + 2x - 6 + 5 + 20 = 180

                     7x  + 19       = 180            {Subtract 19 from both sides}

                                  7x = 180 - 19

                                  7x = 161               {Divide both sides by 7}

                                    x = 161/7

x = 23

2x - 6 = 2*23 - 6 = 46 - 6 = 40

3x + 5 = 3*23 + 5 = 69 + 5 = 74

2x + 20 = 2*23 + 20 = 46 + 20 = 66

Smallest angle = 40

Answer:

1/8

Step-by-step explanation:

The slope equation for this problem is

y2-y1

--------

x2-x1

So the y2=4, y1=3, x2=8, and x1=0

4-3      =1

-----       --

8-0     =8

Which is 1/8

Answer: 1/8

Step-by-step explanation:

Use the slope formula and slope-intercept form

y = mx + b to find the equation.

y = 1/8x + 3

we are told that the expression for profit is

[tex]p = 1.25n - 475[/tex]-----------------1

the above equation represents the situation

given

profit is  $950

Required

n=number of bars

950=1.25n-475

collect like terms

950-475=1.25n

475=1.25n

divide both sides by 1.25

n=475/1.25

n= 380candy bars

Answer:

Line one is the answer

As you see the first line is steeper

Answer:

Line one

Step-by-step explanation:

In order to find the answer to this question simply plot the points on a graph and compare the lines to see which is steeper.

When you plot the points you will see that lines one slope is lower and goes steeper then line two, which means it's your answer.

Hope this helps.

Answer:

The slope is 1/2

Step-by-step explanation:

The rate of y over the rate of x so it would be y/x. You put the equation y2-y1/x2-x1

Which would look like -3-3/-4-8= -6/-12=6/12 and then you simplify it to 1/2

Answer:

1. the vertex form of your function is f(x)= (x+-2)^2+-7

The vertex is at (2,-7)

2. So, the vertex form of your function is f(x)= (x+-7/2)^2 -41/4

The vertex is at (7/2, -41/4)

Answer:

3) x = 21.33

4) x = 33

5) x = 11

Step-by-step explanation:

3: (3x + 17) + (x + 40) + (2x - 5) = 180

6x + 52 = 180

6x = 128

x = 21.333...

4: 180 / 3 = 60

3x - 39 = 60

3x = 99

x = 33

5: 90 + (6x + 7) + (2x - 5) = 180

8x + 2 = 90

8x = 88

x = 11

Answer:

The first option is correct.

Answer:

x = 10

Step-by-step explanation:

We would use postulates and theorem to figure out 34 = 3x + 4. Once you set 34 equal to 3x + 4, you would solve for x as can be shown below:

34 = 3x + 4

Subtract 4 from both sides.

30 = 3x

Divide both sides by 3.

10 = x

Answer:

10

Step-by-step explanation:

(3x + 4)° = 34°

x = 10

Count from the origin to the center of the parabola. You will notice that there are 4 units.

So, the axis of symmetry is the line x = 4. The equation x = 4 cuts the parabola exactly in half.

Answer:

y= -3/5x + 16

Step-by-step explanation:

slope intercept form: y=mx+b

1. Find the slope: rise over run so 13-19/ 5-(-5) = -3/5

M=-3.5

2. Find the y - intercept by using the point slope form: b= 16

So, y= -3/5x + 16

Answer:

y = 2x+ 4

Step-by-step explanation:

The slope of your line given is 2 and it's y-int is 2 that makes the equation y=2x+2.

Since you want a parrallel line you want the smae slope but with a different y intercept. So the answers is y =2x +4.
