At a packaging facility, small boxes contain vintage video games and large boxes contain Nintendo Switches. Three boxes of Switches and one box of video games weigh 48 pounds. Three boxes of Switches and five boxes
of video games weight 72 pounds. How much does each box weigh?

true? is that what you're asking or do you mean something else?

i think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval

i believe a. 12x≥120 is the answer

this is a direct variation proportion. y = kx

y is the total amount due, k is the constant of variation, and x is the number of texts sent.

plug in the 3.20 and the 16 to solve for the "k". this is the constant of proportionality. it is the value that will not change.

3.20 = k(16). solving you get $.20 per text.

the equation would then be y = .20x
