Answer: The answer is given in the attached figure below.
Step-by-step explanation: Given that the ordered pairs (1,4), (3,12) and(5,20) represents the distance y the Dario walks after x seconds.
We are to plot the given ordered pairs in the co-ordinate plane and to draw a line through them.
As shown in the attached figure below, the distance y the Dario walks after x seconds is plotted on the co-ordinate plane.
The time in seconds is plotted across X axis and the corresponding distance walked by Dario is plotted across Y axis.
The point (1, 4) is represented by A, (3, 12) is represented by B and (5, 20) is represented by C.
Finally, we join the points A, B and C to make a straight line l.
Thus, the attached figure below is the required answer.

Answer:
- <u>u = t-s-v</u> is the right answer.
We are given: Degrees Celsius and degrees Fahrenheit are related by formula
To find : Solve formula for F in terms of C.
Solution: We have ,
First we need to get rid 9 from right denominator.
In order to get rid 9 from right denominator, we need to multiply equation both sides by 9.
9C = 5 (F-32).
Distributing 5 on right side over (F-32), we get 5*F - 5*32 = 5F - 160.
9C = 5F - 160.
Adding 160 on both sides,
9C+160 = 5F - 160+160.
9C+160 =5F
Dividing both sides by 5, we get
(9C+160)/5 =5F/5.
Splitting fraction 1/5, we get
