god bless thank you sa points
Answer:
Plugging in our initial statement values of y = 10 when x = 4, we get:
10 = 4k
Step-by-step explanation:
Divide each side by 4 to solve for k:
10=4k
4 4
k=2.5
Solve the second part of the variation equation:
Because we have found our relationship constant k = 2.5, we form our new variation equation:
y = 2.5x
Since we were given that x = , we have
y = 2.5()
y = 0
