Answer:

Step-by-step explanation:
Given:
After lunch the friends walked 6 3/4 miles before arriving at the end of the trail.
The trail is 14 1/8 miles long.
Question asked:
How long did the friends walk before lunch ?
Solution:
Let the friends walk before lunch in miles = 
As total length of trail is given
, we can conclude:
Total length of trail = The friends walk before lunch in miles + The friends walk after lunch in miles

Subtracting both side by 

Taking LCM of 4 and 8 ,we get 8

Therefore, the friends walk before lunch is
.
Answer:
Bottom left graph
Step-by-step explanation:
Since the y-coordinates are the same, but the x-coordinates are opposites, it is a reflection across the y axis.
Therefore, the bottom left graph is correct.
Answer:
x = 22
Step-by-step explanation:
158 + x + 148 + 32 must sum up to 360 as this is a quadrilateral. Thus:
x + 338 = 360.
Subtracting 338 from both sides, we get x = 22
Answer:
B. -6 ≤ y ≤ 9
General Formulas and Concepts:
<u>Algebra I</u>
- Range is the set of y-values that are outputted by function f(x)
Step-by-step explanation:
According to the line in the graph, our y-values span from -6 to 9. Since both are closed dot, they are inclusive in the range:
Range: [-6, 9] or -6 ≤ y ≤ 9
