Find the value of y for a given value of x, if y varies directly with x.
1 answer:
Answer:
The value of y is 92 . The complete steps of the solution is provided below.
Step-by-step explanation:
We are given with
* y varies directly with X
* If y=128 when x=64.
The equation for direct variation equation is y= k x.
Where 'k' is constant of variation.
By putting the values of x and y, we can find the value for k.
→ 128 = k (64)
Divide both sides by 64.
→ = k
Simplify it.
→ 2= k or k =2
Plug in back 'k' as 2 into the equation y=k x.
We get y=2 x.
We are asked to find the value y when x=46.
Plug in x as 46 into the equation.
⇒ y=2(46)
⇒ y= 92
Thus the answer is 92.
