Enter a piecewise function for the situation. Then complete the table and select the correct graph. A local golf course charges members $20 an hour for the first three hours, $30 an hour for the next two hours, and nothing for the last five hours, for a maximum of 10 hours.

Part 1 out of 3
Express the cost C (in dollars) as a function of the time t (in hours) that a member plays golf at this golf course.

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

a king of hearts and a 2 of spades

it would be 3 0ver 24 very unlikely.
