Suppose y varies directly with x. if y = 3 when x = 2, find y when x = 3.
9/2 2-3 3/2 2/9

y=9/2

Step-by-step explanation:

As, y varies directly with x .

so, x & y  must  be proportional to each other.

so,

3/2=y/3

y=(3.3)/2

y=9/2

First option:

Step-by-step explanation:

A Direct variation equation has this form:

Where "k" is the constant of variation.

In this case, to find "k", we need to subsitute and into the equation   and solve for "k":

Now, in order to find the value of "y" when , we need to substitute this value and the value of "k" into the equation  . Then:

there are 25 people coming to the party

step-by-step explanation:

the text says that there will be 22 children at this party, 1 teacher, and 2 parents. so if you add them all together (22+1+2) it will equal 25. (=25)

answer is  

a.

7 in. x 11 in.

hope you get this right.
