Answer:
f(x) = {-x for x < 2; 2x-3 for x ≥ 2}
Step-by-step explanation:
The blue line extending to the left has a slope of -1 and a y-intercept of 0. Its equation is y = -x. That part of the definition of f(x) is applicable for values of x less than 2. (The open dot at (2, -2) tells you that point is not included.)
The red line extending to the right has a slope = rise/run = 2/1 = 2. The y-intercept can be found by extending the line to the y-axis, or from the computation ...
b = y -mx
b = 1 -2(2) = -3 . . . . . for the point (x, y) = (2, 1)
Then the slope-intercept equation for the red line is ...
y = 2x -3
That part of the definition of f(x) is applicable for values of x ≥ 2. The solid dot tells you the point (2, 1) is included.
Putting these parts together, we get ...

Answer:
James Spent 25 hours driving from Philadelphia to New Orleans.
Step-by-step explanation:
Given:
Distance from Philadelphia to Orlando = 986 miles
Time required to travel Philadelphia to Orlando = 14.5 hrs
Distance from Orlando to New Orleans = 714 mile.
We need to find the total amount of time James spent driving from Philadelphia to New Orleans.
Solution:
First we will find the average speed from Philadelphia to Orlando.
We know that;
Speed is equal to distance divided by time.
framing in equation form we get;
average speed from Philadelphia to Orlando =
Now given that he traveled with same speed from Orlando to New Orleans.
So we will find the time required from Orlando to New Orleans.
We know that;
Time is equal to Distance divided by speed.
framing in equation form we get;
time required from Orlando to New Orleans =
Now we will find the total time James spent on driving from Philadelphia to New Orleans.
the total time James spent on driving from Philadelphia to New Orleans is equal to sum of Time required to travel Philadelphia to Orlando and time required from Orlando to New Orleans.
framing in equation form we get;
the total time James spent on driving from Philadelphia to New Orleans = 14.5 + 10.5 = 25 hours.
Hence James Spent 25 hours driving from Philadelphia to New Orleans.

Answer:
(3.8)
Step-by-step explanation:
Given
See attachment for grid
Required
Which point is on Veronica's path
On the attached grid, I plotted each of the coordinate pair (i.e the given options, A to D) on the grid.
By observation. we can see that:
A is on the vertical line (y intercept)
B is on the second quadrant
C is just few points to the left of the given path
D represents Verlonda's house
<em>Hence, the required coordinate pair is: (3.8)</em>
