What is the slope of (15,9), (-14,-9)

1 answer:

8 0

The formula for slope:

m = $\frac{y_{2} - y_1 }{x_2-x_1}$

$\frac{-9-9}{-14-15}$

-9-9 = -18
-14-15 = -29

$\frac{-18}{-29}$

Jina wanted to study how the area of a rectangle changes with the length if it’s width is fixed. She computed the areas of sever

olganol [36]

Answer:

The domain and the range of the function are, respectively:

$Dom\{f\} = [0\,m,5\,m]$

$Ran\{f\} = [0\,m^{2}, 10\,m^{2}]$

Step-by-step explanation:

Jina represented a function by a graphic approach, where the length, measured in meters, is the domain of the function, whereas the area, measured in square meters, is its range.

$Dom\{f\} = [0\,m,5\,m]$

$Ran\{f\} = [0\,m^{2}, 10\,m^{2}]$
