Answer:

Step-by-step explanation:

F=Fair cost, r=ride, U=uber cost. I=initial money

F=10+3r

The money you currently have($80) minus the $10 uber fee should be greater than 0 after the rides you went to. Here's the equation:

I-U>=10+3r

80-10>=10+3r

70>=10+3r=>Complex inequality

60>=3r

r<=20=>20 rides

Answer:

(4, -7)

Step-by-step explanation:

Maybe you want the solution to this system of equations.

About the easiest way to obtain it is to use a graphing calculator.

(x, y) = (4, -7)

_____

<em>Additional comment</em>

Since one of the equations gives an expression for y, it is a simple matter to substitute that for y in the other equation.

4x +(-2x +1) = 9

2x = 8 . . . . . . . . . . subtract 1 and simplify

x = 4

y = -2(4) +1 = -7 . . . use the first equation to find y
