Question

X varies directly as y square given that x = 3 when Y = 4 then value of x and y = 6 will be​

Answer 1

Step-by-step explanation:

When x varies directly with y, that means the relationship between x and y is of the form

   x = a * y

where "a" is a constant. We are given that when x=7, y=10; thus, we can write 

   7 = a * 10, so a = 7/10 or 0.7

Now we can find the value of x when y=4 because we know a=0.7 and y=4; you substitute these into x = a * y and you have your answer ... give it a try.
