Concept explainers
To find: For the given value of x determine the y .
Answer to Problem 20PPE
The value of y is 224 when
Explanation of Solution
Giveninformation:
Suppose y varies directly with x.
Explanation:
Direct variation is in the form of
Let's divide with x to obtain the value constant of variation:
Let the direct variation equation;
y=kx
Putting the value of y and x;
Now, multiply both sides by −2 to solve for k;
Putting the value in the equation y=kx
The equation
If
Therefore, the value of y is 224 when
