Answer:
4 miles
Step-by-step explanation:
<u>Walking:</u>
Distance = d miles
Rate = 4 mph
Time = t hours

<u>Biking:</u>
Distance = d miles
Rate = 10 mph
Time
hours (convert minutes to hours)

Hence,

Therefore, the distance to friend's house is

and the total distance of the round trip is

It will be graph one because your y intercept is where the liner equation meets the line which is -2 and the graph increases by 1
The negative in a = -2 for answer A represents a reflection over the x-axis.
What does the cosine graph usually look like?.....It goes through point (0,1) and decreases.
The graph shown goes through point (0,-2). Since there are no vertical or horizontal shifts, the graph has an amplitude of 2 and reflects over the x-axis.
a=2 for answer D does not represent the reflection over the x-axis.
Answer:
y=-2/7x+1/7
Step-by-step explanation:
Find the slope first
-1-1/4+3
-2/7
m=-2/7
y=-2/7x+b
1=-2/7(-3)+b
b=1/7
