Given y inversely proportional to x and x = 3 for y = 4, what is x if y = 12?
y= 12
12/4=3, then use that 3 to multiply by the given x value which is also 3
3 x 3 =9
answer is x=9
y= 12
12/4=3, then use that 3 to multiply by the given x value which is also 3
3 x 3 =9
answer is x=9
Answer:
x = 1
Step-by-step explanation:
Given that;
y inversely proportional to x. This means that as y increases, x decreases and vice versa. Then;
y = k/x
where k is the constant of proportionality
if x = 3 for y = 4 then
4 = k/3, k = 12
y = 12/x. If y = 12 then
12 = 12/x
12x = 12, x = 1
