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

A two-story building measures 21 feet from the ground.Ascale model shows the building to be 3 inches tall. How many inches would
jasenka [17]

Answer: 12\ inches

Step-by-step explanation:

Let be "x" the height inches (in the model) of a 84 foot building.

According to the information provided in the exercise, we know that the height of a two-story building is 21 feet and in the scale model its height is 3 inches.

Knowing this, we can set up the following proportion:

\frac{3}{21}=\frac{x}{84}

The final step is to solve for "x" in order to calculate its value. We get that this is:

\frac{3}{21}=\frac{x}{84}\\\\(84)(\frac{3}{21})=x\\\\x=12

Therefore,  an 84 foot building will be 12 inches tall in the model.

I’ll give brainliest
Natali5045456 [20]

Answer:

C. C = 3P

Step-by-step explanation:

C = total costs

P = number of popsicles

Unit price of 1 popsicle = $3

To get the total cost of popsicles, we need to multiply the number of popsicles bought by the price of each popsicles

Total cost of popsicles = number of popsicles × unit price

Thus, the question would be written as:

C = 3P
