If y=15 when x=5, find y when x=7, given that y varies directly with x.
Oxana [17]

Answer:

when x = 7, y = 21

Step-by-step explanation:

This is about direct variation. If y varies directly with x, then there is a constant  factor of variation, k. The constant of variation can be found by ʸ⁄ₓ

k = ʸ⁄ₓ

k = ¹⁵⁄₅ = 3

Now that we have found k, we simply multiply x by it to find y (this is because y is directly proportional to x). We plug in our x = 7 to find y at this point.

y = 3x

y = 3(7)

y = 21

K/5+14=13<br> what is the answer and how you got the answer.
abruzzese [7]

Answer:

\frac{k}{5+14} = 13 : k = 247\\

Step-by-step explanation:

\frac{k}{5+14} = 13

Multiply both sides by 19:

\frac{19k}{5+14} = 13 * 19

Simplify:

k = 247
