The answer is C. 5x

350 / 70 = $5 per magazine

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
Svetradugi [14.3K]

Answer:

<u>Option A:</u>

R(x)=20x^2+300x+1080

Explanation:

The revenue, R(x) is the product of the number of teams who entered the tournament, T(x), times the entry fee paid by each team, F(x); then you can write:

  • R(x)=T(x)\times F(x)

Thus you must multiply the two functions (polynomials):

  • R(x)=(4x+24)\times (5x+45)

Use distributive property:

R(x)=(4x+24)\times (5x+45)=(4x)(5x)+(4x)(45)+(24)(5x)+(24)(45)

Simplify:

R(x)=(4x)(5x)+(4x)(45)+(24)(5x)+(24)(45)=20x^2+180x+120x+1080

Add like terms:

R(x)=20x^2+180x+120x+1080=20x^2+300x+1080

I don't get what f(-10) means
m_a_m_a [10]
It wants you to complete the function using -10 for x. . .

e.g: f(x) = 1/2x + 2

f(-10) = 1/2(-10) + 2
f(-10) = 3
