C. 5 miles
Since we need to find how many miles they ran together, let us convert feet to miles. Sarah's length is already in miles so we'll leave it that way.
Jaime ran 15840 feet. We are given how many feet are there in one mile (5280), so we need to find how many miles are there in 15840 feet.
x = 15840 / 5280 = 3 miles.
So, Jaime ran 3 miles and Sarah ran 2 miles.
That means that together they ran 3 + 2 = 5 miles.
Pat a) The graph in the attached figure
The slope is
The y-coordinate of the y-intercept is
Part a) Which line represents the linear equation ?
To graph the linear equation find the intercepts
we know that
The y-intercept is the value of y when the value of x is equal to zero
The y-intercept is the point
The x-intercept is the value of x when the value of y is equal to zero
The x-intercept is the point
Plot the intercepts to graph the linear equation
see the attached figure
Part b) Rewritten in slope-intercept form
The equation of the line into slope intercept form is equal to
m is the slope
b is the y-coordinate of the y-intercept
convert to slope intercept form
isolate the variable y
(y x 2) -x
