Answer:
60 in = 240 ft
Step-by-step explanation:
240/4 = 60
—
15 x 4 = 60
9 x 4 = 36
60 x 4 = 240
13 x 4 = 52

Answer:
Third item in the list
Step-by-step explanation:
Third function: f(x) = x + 9. If we substitute 14 for x, we get f(14) = 14 + 9 = 23.
Answer:
Step-by-step explanation:
The table shows a set of x and y values, thus showing a set of points we can use to find the equation.
1) First, find the slope by using two points and substituting their x and y values into the slope formula,
. I chose (-3, 13) and (0,17), but any two points from the table will work. Use them for the formula like so:

Thus, the slope is
.
2) Next, identify the y-intercept. The y-intercept is where the line hits the y-axis. All points on the y-axis have a x value of 0. Thus, (0,17) must be the y-intercept of the line.
3) Finally, write an equation in slope-intercept form, or
format. Substitute the
and
for real values.
The
represents the slope of the equation, so substitute it for
. The
represents the y-value of the y-intercept, so substitute it for 17. This will give the following answer and equation:
