Answer:

The midpoint is (-3, 1/2)

Step-by-step explanation:

To find the x coordinate of the midpoint, add the x coordinates of the endpoint and divide by 2

(2+-8)/2 = -6/2 = -3

To find the y coordinate of the midpoint, add the y coordinates of the endpoint and divide by 2

(9+-8)/2 = 1/2

The midpoint is (-3, 1/2)

the absolute value of -1 is 1 and the absolute value of 5 is 5 since its still positive. I could be wrong so double check with someone else

the absolute value of -1 is 1 and the absolute value of 5 is 5 since its still positive.

Add :

-1.25 + 2.5 = 1.25

For plotting the first one we first need to see the integer as here is 1 we will move to 1. Now, here it is given 0.25. Each line between 1 and 2 has 10 numbers gap so, as it 25 > 20 and 25 < 30. So, we should plot it between the 2nd and the 3rd line. As it is 5 it should be in between the line.

Refer the plotting for better identification

Add :

4.2 + (-0.4)

4.2 - 0.4

3.8

For plotting this one we will move to 3 than it has 8 < 10 so it should be plotted within the first dot.

a+b+c is the formula for calculating the perimeter of a triangle:)

Step-by-step explanation:

Let Stan's age be x, Mark's age be (x + 1) & Wayne's age be (x + 2).

⇒x + (x + 1) + (x + 2) = 111

⇒x + x + x + 1 + 2 = 111

⇒3x + 3 = 111

⇒3x = 111 - 3

⇒3x = 108

⇒ x = 108/3

⇒ x = 36

Answer:

Mid point is (0.5, 4.5)

Step-by-step explanation:

Formular:

[tex]{ \bf{mid - point = ( \frac{x_{1} + x _{2} }{2}, \: \frac{y_{1} + y_{2} }{2} ) }}[/tex]

x1 is 5

x2 is -4

y2 is 6

[tex]{ \sf{mid - point = ( \frac{ 5 + ( - 4)}{2}, \: \frac{3 + 6}{2} ) }} \\ \\ = { \sf{( \frac{1}{2} , \: \frac{9}{2} )}} \\ \\ = ({ \sf{0.5, \: 4.5)}}[/tex]

Answer:

-2x^2-8x+12

Step-by-step explanation:

f(x)=3x^2-2x+4

g(x)=5x^2+6x-8

(f-g) (x)= 3x^2-2x+4 - (5x^2+6x-8)

Distribute the minus sign

(f-g) (x)= 3x^2-2x+4 - 5x^2-6x+8

Combine like terms

          =-2x^2-8x+12

Answer:

[tex] - 2( {x}^{2} - 4x + 6)[/tex]

Step-by-step explanation:

Answer:

b. at least one plane has critical cracks.

Answer:

8=$16

Step-by-step explanation:

6=$12

divide both sides by 6

1=$2

so one pound equals $2 so if 6 pounds equals $12 just add 2 pounds to 6 to make it 8 pounds. you added two pounds so that means you have to add $4 to the total witch will give you

8=$16
