For the data in the table, tell whether y varies directly with x. If it does, write an equation for the direct variation.

y=4x

Step-by-step explanation:x                 y

0                0

1                 4

2                8

3                12

From the above data:

we can say that y varies directly with x.

Direct variation states that if y is expressed as the product of some constant number k and x.

i.e y=kx

found it xd it ok yt

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.
