The cost of performance tickets and beverages for a family of four can be modeled using the equation 4x + 12 = 48, where x represents the cost of a ticket. how much is one ticket? $3.00 $4.00 $9.00 $15.00

For this case we have the following equation:

Where the variable "x" represents the cost of a performance ticket.

If we clear "x" of the equation we can know the cost of a ticket.

Subtracting 12 from both sides of the equation we have:

Dividing between 4 on both sides of the equation:

So, the cost of a ticket is $ 9.00

Option C

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1

its (2) option
