A sacle drawing shows a room as 10 cm by 7 cm. the scale of the drawing is 2 cm = 5m. what is the actual area of the room?

25 m by 17.5 m

Step-by-step explanation:

7/2 = 3.5

3.5 * 5 = 15 + 2.5 + 17.5

10/2 = 5

5 * 5 = 25

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.

you,
