Hello from MrBillDoesMath!
Answer:
(3b -a) / ( 1 + b^2)
Discussion:
My best guess is that we are trying to simply this fraction:
( 3 - a/b) / ( (1/b) + b) = => multiply num. and denom. by "b"
(3b - a) / ( (1/b)*b + b*b) =
(3b -a) / ( 1 + b^2)
Thank you,
MrB
2x+6+x=3x+6
3x+6=180
subtract 6 from both sides.
3x=174
divide by 3 on both sides.
x=58
Answer:
M=(4,112)=(4,5.5) A
Step-by-step explanation:
The midpoint for two points P=(px,py) and Q=(qx,qy) is M=(px+qx2,py+qy2).
We have that px=3, py=2, qx=5, qy=9.
Thus, M=(3+52,2+92)=(4,112).
I think it would be y plus 3 times 2 equals 5x. I'm not sure if that is what they are asking for.
