What two numbers multiply to 80 and add to 28

answer: idk

step-by-step explanation:

answer4 to the second power is 16

and 4 to the third power is 64,

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
