How do i use systems of equations to eliminate two problems that are: -9x+2y=-24 and -x+2y=8
1 answer:
Eliinate y's
multiply top eqatyion by -1 and add to 2nd
9x-2y=24
<u>-x+2y=8 +</u>
8x+0y=32
8x=32
divid both sides b y8
x=4
sub back
-x+2y=8
-4+2y=8
add 4 to both sides
2y=12
divide both sides by 2
y=6
(x,y)
(4,6)

Step-by-step explanation:
<span>5(x – 2)(x + 4) > 0
(5x-10)(x+4)>0
6x -6 > 0
+6 +6
6x >
</span>x<-4 or x>2
triangles angles always add up to 180° that being said,
41+32=73
180-73=107
angle e= 107°
