Answer:X=11/10
Step-by-step explanation:
2x2-10x+7=0
<u><em>4</em></u>-10x+<u><em>7</em></u>=0
11-10x=0
-10x= -11
Divide both side by -10
-10x/-10. -11/-10
Answer= 11/10

Answer:
Slope= 2 / 10 = 1 / 5 = 0.2
y-intercept= (0, -4/5) or (0, -0.8)
Step-by-step explanation:
Hi!
[1] -3x-7y=8
[2] 3x-2y=-44
lets take [1]
-3x-7y=8
-7y=8+3x
-7y-8=3x
3x=-7y-8
No use 3x=-7y-8 and put it in 3x-2y=-44
-7y-8-2y=-44
-9y-8=-44
-9y=-36
9y=36
y=4
then use y in 3x-2y=-44
3x-2(4)=-44
3x-8=-44
3x=-36
x=-12
Therefore, y = 4 and x = -12
