julia took a taxi home from the airport. the taxi fare was $2.05 per mile, and she gave the driver a tip of $6. write a linear equation to relate the total cost of the taxi trip to the number of miles travelled.

(2.05x)+6

Step-by-step explanation:

x would be the miles and you multiply that by your fare per mile and add the 6 dollar tip

The taxi fare was $2.10 per mile, and she gave the driver a tip of $5. Ann paid a total of $49.10.

49.10 = 2.10(x) + 5

44.10 = 2.10(x)

x = 21 miles

4.08%

step-by-step explanation:

{x = -1/2 ,   y = -1

step-by-step explanation:

solve the following system:

{2 x + y = -2

{10 x - 3 y = -2

in the first equation, look to solve for y:

{2 x + y = -2

{10 x - 3 y = -2

subtract 2 x from both sides:

{y = -2 x - 2

{10 x - 3 y = -2

substitute y = -2 x - 2 into the second equation:

{y = -2 x - 2

{10 x - 3 (-2 x - 2) = -2

10 x - 3 (-2 x - 2) = (6 x + 6) + 10 x = 16 x + 6:

{y = -2 x - 2

{16 x + 6 = -2

in the second equation, look to solve for x:

{y = -2 x - 2

{16 x + 6 = -2

subtract 6 from both sides:

{y = -2 x - 2

{16 x = -8

divide both sides by 16:

{y = -2 x - 2

{x = -1/2

substitute x = -1/2 into the first equation:

{y = -1

{x = -1/2
