Answer:

See Below

Step-by-step explanation:

Take the the given information and compare to the question being asked

[tex]\frac{y}{x}[/tex]. So insert the x & y's of both equations (ima do y over x to make it easier)

[tex]\frac{14}{4} =\frac{y}{40}[/tex]

divide 14/4

3.5 = [tex]\frac{y}{40}[/tex]

then multiply both sides by 40 to isolate y

140 = y

Check by reinserting 140 and divide it by 40

Answer:

y= 140

Step-by-step explanation:

if they are directly proportional, that means when one increases/decreases the other does as well.

x increased by multiplying itself by ten. Like before, since they are both directly proportional that means that y is multiplied by 10.

14*10= 140, y=140
