On a math quiz, you earn 10 points for each question answered correctly. In the equation below. x represents the number of questions that you answer correctly on this quiz, and y represents the total number of points you score on this quiz. The relationship between
these two variables is modeled by the equation y - 10x.

A)The value of 10 in the equation

B)The total number of points scored of the exam

C) The number of questions answered correctly on the exam

D)The independent variable cannot be determined from the given information

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50

no solution

step-by-step explanation:

there is not enough information in the problem to solve.

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
