Which of the following are solutions to the equation below? check all that apply. (3x - 5)2 = 19

at least two

step-by-step explanation:

idk what the heck he answer is, i’m just putting this here so i finish my account

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
