Is y=4x proportional or non-proportional

No its nonportional

Step-by-step explanation:

proportional relationship doesn't have any operation between the “k” and “x” where K is the unit rate or the constant of proportionality.

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.
