The constant for variation is k = 3/2 and the equation for the inverse is y = 2/3x
In order to find this, we need to start with the base equation for direct variation. We can then plug in the values and solve for k.
y = kx
4.5 = k(3)
1.5 = k
Now we can model the equation as y = 3/2x. We can then find the inverse by switching the x and y and solving for the new y.
y = 3/2x ----> Switch
x = 3/2y -----> Multiply by 2/3
2/3x = y
Answer:
Step-by-step explanation:
y - 8 = 11(x - 5)
y - 8 = 11x - 55
y = 11x - 43
Answer:
4.2% = 0.042
Step-by-step explanation:
You need to divide the percentage by 100 to get its equivalent decimal:
100% = 1 because
100 ÷ 100 = 1
Therefore,
4.2% = 0.042 because
4.2 ÷ 100 = 0.042
