To plot the two functions, you need to assign values for x. By selecting various x values, corresponding y values are calculated. You then plot the points as shown. The blue line illustrates the function f(x) = 3x, while the orange line indicates f(x) = -x + 4.
These two lines intersect at the coordinates (1,3). To solve for this analytically, we establish the system of equations:
y = 3x
y = -x + 4
By setting these two equations for y equal to each other:
3x = -x + 4
4x = 4
x = 1
Next, substituting x into one of the original equations gives us: y = 3x = 3(1) = 3. Therefore, the solution is (1,3), meaning at a temperature of 3 units, the number of visitors entering matches those exiting the zoo, indicating a balance of one person entering for each one leaving.

Answer:
miles per hour.
Step-by-step explanation:
The jogging path used by Selma is a loop measuring of a mile.
On a certain Monday, Selma completed the loop in an hour.
Thus, by applying the common denominator technique, Selma's running rate in miles per hour will be
miles per hour.
The unit for this measurement is mph, or miles per hour. (Answer)
