Write as an ordered pair. 4x+2y=16 and -4y+x=4
Margaret [11]

Answer:

(4,0)

Step-by-step explanation:

4x+2y=16

-4y+x=4

Multiply the first equation by 2

2(4x+2y)=16*2

8x +4y = 32

Add the 2nd equation

8x +4y = 32

x  -4y     =4

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

9x            =36

Divide each side by 9

9x/9 = 36/9

x=4

Now solve for y

-4y +x =4

-4y +4 = 4

Subtract 4 from each side

-4y +4-4=4-4

-4y =0

Divide by -4

-4y/-4 =0/-4

y=0

(4,0)

HELP PLEASE!!!! A window is 4 feet wide and 8 feet tall. A rectangle is shown. The length of the rectangle is labeled 4 feet. Th
Bingel [31]
First, always draw. You learned to draw in kindergarben (Yes I spelled it like that on purpose LOL) for a reason.

1) Draw your rectangle on a piece of paper or paint. 
2) Scale factor each side to enlarge which means you're going to multiply. 
--- Note if it said 'to reduce' then you would divide.
3) Then find the area by multiplying the two given sides (12 x 6 = 72).
4) Don't forget your unit of measurement - 72ft²

So your answer is D.
