1.what happens to T when h is doubled in the equation T=4h?

A.doubled B.halved C.tripled D.becomes 0 2.what happens to y when x is tripled in the relation y=k/x? a.tripled b.doubled c.halved d.divided by 3 3.if y varies directly as the square of x,how is y changed if x is increased by 20%? a.decreases 44% b.increases 44% c.decreases .44% d.increases .44%

The value of "T" will raise up or it will become 8 multiplied by h or 8h. The answer is A. Doubled, since on first it is "4h" then at the end it became "8h", by which 4 x 2 = 8.

2. Y = k / x Y = k / 3x

When k = 2 and x = 2 on first equation: Y = 2 / 2 Y = 1

on second equation: Y = 2 / 3(2) Y = 2 / 6 Y = 1 / 3

The answer is definitely letter D, on the first equation: Y = k / x when variables k and x are 2, the answer is 1, on the second equation: Y = k / 3x when variables k and x are 2, the answer is 1 divided by 3.
