An input-output table has two sets of numbers, input numbers and output numbers. The same thing is done to each input number to get the output number.

What was done to each of these input numbers to get the output numbers?

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571

step-by-step explanation:

he kicked it up? is this the answer ?

step-by-step explanation:

x= cost per bracelet

number of bracelets * x + shipping charge = total cost
