Convert 5% to .05 multiply that by total and youll get the tax amount and add the to the total then for the tip you multiply .15 by the total and shabam theres your answer
(x, y ) → (- 1, 3 )
The solution to the system of equations is the point of intersection of the 2 lines
From the graph, that is (x, y ) → ( - 1, 3 )
We can confirm by solving algebraically
Since both equations express y in terms of x we can equate the right sides
- x + 2 = - 6x - 3 ( add 6x to both sides )
5x + 2 = - 3 ( subtract 2 from both sides )
5x = - 5 ( divide both sides by 5 )
x = - 1
substitute x = - 1 into either of the 2 equations for y-coordinate
y = - x + 2 = 1 + 2 = 3
solution is (x, y ) → (- 1, 3 )

Answer:
7.5 hours
Step-by-step explanation:
16 mph = 16 miles per hour
how much time does he spend commuting to, and returning from, work each day = 60(2) = 120 miles
120/16
= 7.5 hrs
