Question 4. Problem 15: For the function, y varies directly with x. Find the constant of variation. Then find the value of y when x = -0.3. y = 4 when x = -3

The constant of variation is -4/3 and the value of y when x = -0.3 is 0.4 How to determine the value of y when x = 4? The given parameters are: y is directly proportional to x. This is represented as: y = kx Where k represents the constant of variation When x = -3, y = 4. This gives 4 = k * -3 Divide both sides by -3 k = -4/3 This means that the constant of variation is -4/3 Substitute k = -4/3 in y = kx y = -4/3x When x = -0.3, we have y = -4/3 * -0.3 Evaluate y = 0.4 Hence, the value of y when x = -0.3 is 0.4 Read more about variation at: https://brainly.com/question/6499629 #SPJ1 Reply
