Bill wants to rent a car. rental company a charges $45 plus $1 per mile driven. rental company b charges $25 plus $2 per mile driven. after how many miles driven will the price charged by each company be the same?

20 miles

Step-by-step explanation:

I set this up as a linear equation:

45 + x = 25 + 2x

1. subtract x from both sides

45 = 25 + x

2. subtract 25 from both sides to isolate the variable

20 = x

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.
