Answer:

Step-by-step explanation:

-7x-2y=-13

x-2y=11

(subtract the first inequality from the second)

-7x-x = -8x

-2y-(-2y) = 0

-13-11= -24

-8x=-24

x=3

(now place the x value into the second inequality)

3-2y=11

-2y=11-3

-2y=8

y=-4

x=3

y=-4

Answer: x=3, y= -4

Steps: The two equations are," -7x-2y=-13 " and " x - 2y = 11 "

Let's take the 2nd equation and find for x

x - 2y = 11

x= 11 + 2y

Now place the value of x in the first equation:

-7(11+2y) - 2y = -13

-77 - 14y - 2y = -13

- 16y= -13 + 77

y= 64/-16

y= -4

Now that you found the value of y, place it again on the 2nd equation:

x - 2(-4) =11

x + 8= 11

x=11-8

x= 3

If C is the midpoint of EF, C has coordinate -8, F has coordinate 4, then find the coordinate of E
ycow [4]
<h3>Answer:    -20</h3>

==========================================================

Work Shown:

Let x be the location of E on the number line.

Since C is the midpoint of E and F, this means we can find C's location by adding E and F together and dividing that sum by 2

midpoint = (endpoint1 + endpoint2)/2

C = (E+F)/2

Plug in E = x, C = -8 and F = 4. Then solve for x

C = (E+F)/2

-8 = (x+4)/2

(x+4)/2 = -8

x+4 = 2(-8) .... multiplying both sides by 2

x+4 = -16

x = -16-4 .... subtract 4 from both sides

x = -20

The location of point E on the number line is -20

-------------

As a check, lets add E and F to get E+F = -20+4 = -16

Then cut this in half to get -16/2 = -8, which is the proper location of point C

This confirms our answer.

Suppose you want to represent a triangle with sides 12 feet, 16 feet, and 18 feet on a drawing where 1 inch = 2 feet. How long s
slega [8]

Answer:

<u>The correct answer is C. 6, 8 and 9 inches.</u>

Step-by-step explanation:

1. Let's review all the information provided for answering the questions properly:

Length of the sides of the triangle = 12 feet, 16 feet and 18 feet.

Scale used : 1 inch = 2 feet.

2. How long should the sides of the triangle be in inches?

For calculating the length of the sides of the triangle in the draw, we use the scale this way:

1st Side = 12 feet

12 feet/2 = 6 inches

2nd Side = 16 feet

16 feet/2 = 8 inches

3rd Side = 18 feet

18 feet/2 = 9 inches

<u>The correct answer is C. 6, 8 and 9 </u>
