If a relationship is not proportional would it have a y-intercept of zero

(hurry! ) which expression is equivalent to the following complex fraction?

What value of x is in the solution set of 4x – 12 s 16 + 8x?

Find the measure of angle y. round your answer to the nearest hundredth. ( type the numerical answer only) a right triangle is shown with one leg measuring 5 and another leg measuring 14. an angle across from the leg measuring 5 is marked y degrees. numerical answers expected!
