The number 7 is the best prediction of the output when the input is 13.

<h3>What is the equation of a line passing through two given points in 2 dimensional plane?</h3>

Suppose the given points are (x_1, y_1) and (x_2, y_2), then the equation of the straight line joining both two points is given by

(y - y_1) = \dfrac{y_2 - y_1}{x_2 - x_1} (x -x_1)

The equation of the line is found as;

\rm y-y_1=  \frac{y_2-y_1}{x_2-x_1}      \\\\ \rm y-9=                                         \frac{31-9}{2+5} (x+5)\\\\ 7y-63 = \frac{31-9}{2+5} (c+5)\\\\ 7y-63=22x+110\\\\ 7y= 22x+173 \\\\ but ,x=13\\\\ 7y=22 \times 13 +173\\\\ y= \frac{1259}{7} \\\\ y= 179

The number of viewers for television show 1 and show 2 is given as f = 14.7(0.94)ˣ and g = 15.2(1.03)ˣ

<h3>What is an exponential function?</h3>

An exponential function is in the form:

y = abˣ

Where a is the initial value of y and b is the multiplication factor.

Let f and g representing the approximate number of viewers, in millions,  x weeks after the tracking begins.

Look at the table showing prices of different items at a store.
kati45 [8]

The types of items that cost less than $3.75 per item are Paperbacks and notebooks.

<h3>How do we determine the price of a unit item in a word problem?</h3>

The price of a unit item can be determined by dividing the total price by the number of units sold.

Given that:

Paperbacks sold 3 units for $10.65;

  • 1 unit will be sold for = $10.65/3 = $3.55

Notebooks sold 4 units for $14.36;

  • 1 unit will be sold for = $14.36/4 = $3.59

Puzzles sold 3 units for $11.85;

  • 1 unit will be sold for = $11.85/3 = $3.95

Picture frame sold 4 units for $15.20;

  • 1 unit will be sold for = $15.20/4 = $3.80

Therefore, from the above calculations, we can conclude that the types of items that cost less than $3.75 per item are Paperbacks and notebooks.
