(x, y) (7,11) (8,13) (9,15) (10,17) determine whether y varies directly with x. if so, find the constant of variation k and write the equation.

  no direct variation

Step-by-step explanation:

The y/x ratio varies, so the variation is not direct.

  11/7 ≠ 13/8 ≠ 15/9 ≠ 17/10

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:

first you will have to convert 3/4 into a decimal

which is .75

then you will have to divide 1.5 by .75

which is 2

no you have to divide
