Answer:
x = 2, y = -1
Step-by-step explanation:
To find x, use elimination.
multiply everything in x - y = 3 by 2
(x - y = 3)2
that will now become 2x - 2y = 6
now line the equations up.
4x + 2y = 6
2x - 2y = 6
Now add everything going down.
4x + 2x is 6x, 2y and -2y cancel out, and 6 + 6 is 12. the equation is now:
6x = 12
divide on each side.
x = 2
to find y, substitute 2 into x - y = 3
2 - y = 3
-y = 1
y = -1

Time taken by Devon is given by
Hence, Devon will complete the entire trip in 3 hours 20 minutes.
Answer:
y = abs (x-5) -4
Step-by-step explanation:
We are shifting the absolute value function
f(x) = |x| to
g(x) = | x +h| + k
where h is a shift left if h > 0
right if h < 0
and k is a shift up if k> 0
down if k< 0
Since the graph is shifted down and to the right
k is <0 and h < 0
where k = -4 and h=-5
