the number of teams who entered in a 3-on-3 charity basketball tournament can be modeled by function t, where x is the number of years since the tournament first started.
t(x)=4x+24
the entire fee paid by each team to enter the tournament can be modelfied by function f, where x is the number of years since the tournament first started.
f(x)=5x+45
which function, r, best represented the total entry fees collected in the sixth year since the tournament first started?
a. r(x)=9x^2+29x+69
b. r(x)=20x^2+1080
c. r(x)=20x^2+300x+1080
d. r(x)=9x+69

Step-by-step explanation:

The number of teams who entered in  basketball tournament

The entire fee paid by each team to enter the tournament

Total entry fees = Number of teams * fee paid by each term

USe FOIL method to multiply it

combine like terms

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w

a) 0,0; 1,1; and 2,2

step-by-step explanation:

these have the exact same coordinates, thus they are the correct function.
