The after-school Activities Club charges $20 to join for the year. It charges a materials fee of $ 6 for each activity you choose. Write a linear function to model the cost, c, of joining the club and choosing t activities. Find the value of the function for t equals negative 3. Explain the meaning of this function value in terms of the situation.

Which linear function models the cost, c, of joining the club and choosing t activities?

A. c = 6t + 20
B. c = 6t - 3
C. c = -3t = 20
D. c = 20t = 6

31 v bucks

step-by-step explanation:

since you bought 25 on friday and 6 on tuesday, you can just add them up.

25+6=31

check your work.

31-6=25

let's call the solutions x₁ = (5 - 2√7)/3 and x₂ = (5 + 2√7)/3

then the equation is (x-x₁)(x-x₂) = 0

if you fill that in you get a lot of numbers which you can recognize as ax²+bx+c=0.

step-by-step explanation:

you can see that a=1 (there is just an x²)

b = (-5 -2√7 + 2√7 - 5)/3 = -10/3

c = -2√7)/3 ) * (-5+2√7)/3) = -1/3

so your answer is 3x^2 – 10x – 1 = 0
