The value of Y varies directly with X which function represents the relationship between X and y if y=18 when x=30.

A. Y =12x

B.y=5/3x

C. Y=48x

D. Y=3/5x






Is the following pair of lines parallel or perpendicular or neither.
2y=5x+14
Y+2=-2/3(x+10)






graph the function.
2y+7=3(x+5)

Answer :

Answer:

D. Y=3/5x

Step-by-step explanation:

Y~X, y is directly proportional to x and vice versa

- Y/X= constant

- Y/X=18/30 simplify

- Y/X=3/5 multiply x on both sides

- Y= 3/5x
