Select the format which represents proportional relationship. a.) ax + by = c b.) y = mx c.) y = mx + b give me the write answer im in the middle of a test and i babe all as in math and i dont want to get dropped to a b so this one is worth 25 points.

B

the equation representing proportional relationship is

y = mx

the equation must pass through the origin which y = mx does

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°

step-by-step explanation:

descending order means to order the polynomials from the term with the largest exponent to the term with the smallest exponent.  

therefore, the correct answer is d.
