Answer:
A) speed = 10.5 miles per hour
B) Time taken by him = 1.714 hours
C) Distance = 10.5 mph × 7 hours = 73.5 miles
Step-by-step explanation:
Given as :
The distance cover by David = miles = 5.25 miles
The time taken by David = hours = 0.5 hours
Let the speed = x mile per hour
So, Distance = Speed × Time
A)or, Speed =
Or, Speed =
∴ speed = 10.5 miles per hour
<u>B) Again The Distance cover by him = 18 miles</u>
SO, with speed 10.5 miles per hour
The Time taken by him = hours
Or, Time taken by him = hours
∴ Time taken by him = 1.714 hours
<u>C) Again the Time taken by him = 7 hours </u>
So, Distance cover by him with speed 10.5 mph
Or, Distance = 10.5 mph × 7 hours = 73.5 miles
A) speed = 10.5 miles per hour
B) Time taken by him = 1.714 hours
C) Distance = 10.5 mph × 7 hours = 73.5 miles Answes
<u>Given:</u>
Given that the graph of a linear function.
We need to determine the equation of the graph in slope intercept form.
<u>Slope</u>:
Consider any two coordinates from the equation of the line to determine the slope.
Let the two coordinates are (-4,3) and (4,-1)
The slope can be determined using the formula,
Substituting the coordinates in the above formula, we get;
Thus, the slope of the equation is
<u>Value of y - intercept:</u>
The value of y - intercept is the value of y when x = 0.
Hence, from the graph, it is obvious that the value of y when x = 0 is 1.
Hence, the value of y - intercept is 1.
Thus, y - intercept is
<u>Equation of the line:</u>
The equation of the line can be determined using the formula,
Substituting the slope and the y - intercept
Thus, we get;
Thus, the equation of the line is
