Mathematics

F(x)= -4x+9

Multiply f*x

xF=9+4x

Solve for X: -4x+xF=9+4x-4x=0

Combine like terms: -4x+4x=0

-4x+xF=9+0= 9

-9+-4x +xF = 0.

X2/y+x2/ for x=6,y=-4 and z=-2
hodyreva [135]
X2/y+x2/
x=6
y=-4
z=-2

6✖️2/-4➕6✖️2
6✖️2=12
This goes for both due to PEMDAS
Now it looks like this:
12/-4➕12

-4➕12= 8

Now it looks like this:
12/8

Since there was no z then -2 wouldn’t be needed

So your answer would be 12/8

Hope this helps! :3
