Determine whether each equation represents a linear or non linear function, help me plzz y=3x

y=4x-1

y=x²+1

y=0.75x+2

y=0.5x³

y=3x - Linear Function

y=4x-1 - Linear Function

y=x²+1 - Non-Linear Function

y=0.75x+2 - Linear Function

y=0.5x³ - Non-Linear Function

(For a function to be linear, both x & y must equal 1.)

i don't even know man. edge inuity be messing with us. i had to ask a question too.

81 seats

step-by-step explanation:

if you multiply 0.65 times 125 then you get 81.5 seats. well since you can't have half of a seat you have to round down and get 81 seats in the no children zones. that leave 44 seats outside of the no children zone.
