F(x)=10 would be the easiest way to put that
4x(-2) + 4 x 7 4x5 + 2x(-1) =[-8 20]
[28 -2 ]
In probability?
each arrow shows what % chance it is.
uhhh here’s a pic off google to help
it can be more than 2 arrows and as many times as you like.
8z − 4 = 7z
move 8z to the other side
sign changes from +8z to -8z
8z-8z-4=7z-8z
-4= 7z-8z
-4= -z
mutiply both sides by -1 to get +z
(-4)(-1)= (-z)(-1)
Answer:
z= 4
