<h3>Answer: 18</h3>

==========================================================

Explanation:

2 cm on paper (or on screen) represents 3 meters in real life.

The backyard is 2 cm horizontally across on the screen, so it's 3 meters across in real life. This is the shorter dimension.

The longer dimension is 6 meters. We can think of it like this

2 cm : 3 meters

2*2 cm : 2*3 meters .... multiply both sides by 2

4 cm : 6 meters

The real backyard is 6 meters by 3 meters to give an area of 6*3 = 18 square meters.

Whats the answer to 3,000(6-2) + 3,000

yuradex [85]

The answer is 15000

$3000 \times ( 6 - 2) = 12000 + 3000 = 15000$
3000*6=1800
3000*-2=-6000
18000-6000=12000
12000+3000=15000

The graph models function R. The table of values models function S. Which statement is true about these functions?

vagabundo [1.1K]

Answer: OPTION D.

Step-by-step explanation:

The rate of change of a linear function is also known as "Slope".

The slope can be calculated with the following formula:

$m=\frac{y_2-y_1}{x_2-x_1}$

Choose two points on the function "R" graphed:

$(1,0)\\(0,-3)$

You can say that:

$y_2=-3\\y_1=0\\\\x_2=0\\x_1=1$

Substituting values into the formula, you get:

$m=\frac{-3-0}{0-1}=3$

Choose two point from the table that models the function "S":

$(4,21)\\(6,31)$

You can say that:

$y_2=31\\y_1=21\\\\x_2=6\\x_1=4$

Substituting values into the formula, you get:

$m=\frac{31-21}{6-4}=5$

Therefore, you can conclude that the function "S" has a greater rate of change than Function "R".
