The error is in step 2. -x and 3x combine to make 2x, not 4x
The rule for a 90 degree rotation is
(x,y)——>(-y,x)
So let’s take the coordinate (-5,-1) and let’s replace the x and y places together!!!
So that would give us -1•-1 which is just 1
Then -5•1 which is just -5
So the answer is
(1,-5)
I don’t know maybe try google
Answer:
X=2
Step-by-step explanation:
3X+8 = 4X+6
3(2)+8=14.......4(2)+6=14
