Answer:
Step-by-step explanation:
I assume that XY is midsegment of a triangle, then MO = 2 XY
9x - 20 = 2( 3x - 4 )
9x - 20 = 6x - 8
3x = 12
x = 4
MO = 9(4) - 20 = 16 units
Answer: Slope=-2/3

Answer:
Step-by-step explanation:
-3m*n+4m-3 when m=2:n=-2
-3(2)*(-2)+4(2)-3=
12+5=17
If anything there might be an eraser icon (modification notes) so you might want to click on that and read it. If not, post what it says or give the math teacher a call. I hope this helps!
Answer is 188
3x2 - 5xy + 5y2
Now put x = -6 and y = 2
3(-6)2 - 5(-6)(2) + 5(2)2
3(36) - 5(-12) + 5(4)
108 + 60 + 20
188
