suppose that y varies directly as x . if y is 24 when x is 6, find the constant of variation and the direct variation equation
1 answer:
Answer:
Step-by-step explanation:
Direct variation can be modeled by y = kx where k is the constant of variation!
So to solve for k all we need to do is substitute in the value for y and x that are given.
So according to the problem y = 24 when x = 6
24 = 6k
Divide both sides by 6
k = 4
So the constant of variation is 4
The direct variation equation would then be
y = 4x

Answer:
y = 2
Step-by-step explanation:
Given
= 
( cross- multiply )
10(2y - 1) = 15y ← distribute left side
20y - 10 = 15y ( subtract 15y from both sides )
5y - 10 = 0 ( add 10 to both sides )
5y = 10 ( divide both sides by 5 )
y = 2
