In one U. S. city, the taxi cost is $2 plus $0.50 per mile. If you are traveling from the airport, there is an additional charge of $6.00 for tolls. How far can you travel from the airport by taxi for $38.00?

60 miles

Step-by-step explanation:

the equation for the cost for traveling from the airport can be represented by y= .50x + 2 + 6

where y is the final cost and x is the amount of miles. plug in 38 to y to get 38 = .50× +2 + 6. Solve for x.

38-6 =.50× +2

32 =.50x +2

32-2=.50x

30=.50x

30/.50=x

60=x

therefore, the 60 miles is how far you can go with $38

6, 10

9, -13

12, -21

18, -23

step-by-step explanation:

you just add 6 to the x-coordinate and subtract 10 from the y-coordinate.

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3
