The x-variable will be eliminated when adding the system of equations since -2x + 2x = 0

The sum of the system of equations is 4y = -12, since 11y + -7y is -4 and -13 + 1 = -12

y = -3, since when you solve for y in 4y = -12 you get -3 (divide both sides by -4)

The first statement is true because 2x + -2x = 0

3rd statement is also true.

Statement 5 is also true.

Find the coordinates of H if X(-8, 4) is the midpoint of GH and G(2, -9).

skelet666 [1.2K]

Step-by-step explanation:

Hey there!

The given midpoint is; X(-8,4) and G(2,-9).

To find: H

Now; You need to use formula for midpoint.

$midpoint(x) = ( \frac{x1 + x2}{2} , \frac{y1 + y2}{2} )$

Put all values.

$( - 8,4) = (\frac{ 2 + x}{2} , \frac{ - 9 + y}{2} )$

As they are equal, their corresponding elements are equal.

$- 8 = \frac{2 + x}{2}$

$- 16 - 2 = x$

x = -18

$4 = \frac{ - 9 + y}{2}$

$4 \times 2 = - 9 + y$

$8 + 9 = y$

$y = 17$

Therefore, y = 17.

Therefore, H =( -18,17).

Hope it helps....

A square rug has an area of 225ft. How long is each side of the rug?

klio [65]

The area formula is b x h, but since its a square the area would be side squared.

here side squared = 225 ft

Square root of 225 is 15, so each side of the rug measures 15 feet

3 numbers:by 1000, etc

Ex 0.4= 4/10 = 2/5

Answer:

B = j + H

Step-by-step explanation:

Given:

j = - H + B

Solve the equation for B

j = - H + B

Add H to both sides of the equation

j + H = - H + B + H

j + H = B

B = j + H
