There is a few ways to do this but I am going to use the variation equation.
Variation Equation: y = kx First we need to find k, which is the constant of variation 5 = k50 5/50 = k 1/10 = k k= 1/10
Now that we have found the constant of variation, we can find how much the spring will stretch with 170 pounds. y = kx y = (1/10) times 170 = 17 inches
The product is the result of multiplication. the product of a number and 48 --- 48x ---is (means equals) - 18 so its gonna be: 48x = -18 x = -18/48 x = - 3/8 <== ur number
