If y varies inversely as x and y = -3 when x = 6, find x when y is 36?

Question

show work

Answer 1

ok... PEOPLE! inversly means the product between x and y are same....

so when y=-3 and x=6
-3*6=-18
-18/36=-1/2 or -0.5

Answer 2

d. 18 is the respond. enable us to make sure the stairs. y = 3 and x = 6 and we are presented that y is inversely proportional to x. So y / x = a million/2 So, on a similar time as x = 36, y = x. a million/2 = 36.a million/2 = 18

Answer 3

If y varies inversely as x, therefore :

y = k/x (where k is a constant)


y= -3 when x=6

y = k/x (Substituting values of y and x)
-3 = k/6
-18 = k

Now that we know the value of the constant k = -18
Find x when y = 36

Applying
y = -18 / x
36 = -18 / x
36x = -18
x = -18 / 36
x = - 1/2
x = - 0.5

Hope you understand.

Answer 4

if the variation is inverse then the product of the variables is constant
(6)(-3)=(x)(36) and so x=-18/36 or –1/2
so remember if ‘x’ and ‘y’ vary directly the quotient x/y is always the same ans
if ‘x’ and ‘y’ vary inversely the product x*y is always the same

Answer 5

if y = -3, then x = 6

if y now become 36 you have multiplied by -12

However y varies INVERSELY so you must DIVIDE x by -12 to find the new x

Answer 6

I can think of two possible answers....y could be -9 and y could be -18.
