Answer:
y=5/4 x
The slope is 5/4
Step-by-step explanation:
To solve this problem we need to find the equation of the line, y=mx+b
We've been given a table with several points, so we can use two of them to perform our calculus.
To obtain the slope we need to use the equation of slopes:
Where (x1,y1) =(4,5) and (x2,y2)=(8,10)
m= (10-5)/(8-4)=5/4
To obtain b we can use the point (x2,y2)=(8,10) in the equation.
10=5/4 *8 +b
b=0
Hence our line has the following equation:
y=5/4 x
A) 4√3 + 6
B) 6√3 + 4
C) 6√6 + 3
Answer:
x = 7
Step-by-step explanation:
3x - 17 = 25 - 3x
Get the x's on one side and the integers on the other
3x + 3x = 25 + 17
6x = 42
x = 7
The distance traveled by train will be 78 mph will be 13 miles.
The distance covered by the particle or the body in an hour is called speed. It is a scalar quantity. It is the ratio of distance totime.
We know that the speed formula
Speed = Distance/Time
If a train travels at 78 mph for 10 minutes.
Convert the number of minutes into hours.
10 minutes = 10 / 60 hours
10 minutes = 1/6 hours
Then the distance traveled by train will be
78 = D / (1/6)
D = 78 / 6
D = 13 miles
The distance traveled by train will be 78 mph will be 13 miles.
