12 1/4 because the original answer is 12 3/12 but you should simplify it to 12 1/4.
Y=2/x. this equation has degree -1 whereas linear functions have degree 1
y=6x²-7 is nonlinear as it is degree 2
Answer: 4
Try just dividing 23/5 and you’d get 4 something. But since 5.97 is close to 6 you can also mentally divide 23/6 and get 3something (it’d be really close to 4)
Yes it is a 90 degree rotation clockwise.
