1. we can add them to eliminate y's
3x-4y=-16
<u>-x+4y=24 +</u>
2x+0y=8
2x=8
divide by 2
x=4
sub back
-x+4y=24
-4+4y=24
add 4 both sides
4y=28
divide by 4
y=7
(x,y)
(4,7)
3.
add them to eliminate y's
-5x+3y=12
<u>-2x-3y=-33 +</u>
-7x+0y=-21
-7x=-21
divide both sides by -7
x=3
sub back
-2x-3y=-33
-6-3y=-33
add 6 to both sides
-3y=-27
divide both sides by -3
y=9
(x,y)
(3,9)
1. (4,7)
3. (3,9)
Answer:
12 Percent of 7,200 is 864. If you multiply that by 52 (Weeks in 2011) it will be $44,928
A. is (-5, -3)
You always name the coordinate by going left and right (along the x-axis) first and then up and down (the y-axis). That's because the first point in the coordinate is the x-coordinate and the second point is the y-coordinate.
You can remember this by thinking "you always walk to the elevator (left and right), before you ride the elevator (up and down)."
Or another saying is "You crawl (left and right) before you walk"
