First add up all the hours and then minus the answer with the total hour and u get the answer 3 1 by 2
The value of y varies directly as the square of x and y = -12 when x = 2 then the value of y when x = -4 exists y = 24.
<h3>What is meant by direct variation?</h3>
When two variable quantities contain a constant ratio, their relationship exists comprehended a direct variation. It exists said that one variable varies directly as the other. The formula for direct variation is y = kx, where k exists the constant of variation.
The constant value (often written k) relating amounts that rise or fall uniformly together. It exists the ratio of the amounts y and x:
k = y/x.
Put another way: y = kx.
Accordingly, the equation has the form y = kx, where k may be any number.
Substituting y = -12 when x = 2, we get
-12 = k × 2
simplifying the above equation, we get
⇒ k = -6
Therefore, the required equation exists y = -6x.
The value of y when x = -4 is y = -6 × -4 = 24.
