What is the value of x?

enter your answer in the box.

x =

x = 5 cm

Step-by-step explanation:

We can use proportions of similar triangles.  Put the side of the small triangle over the same side of the large triangle

x                 4

=

40                  32

Using cross products

32x = 4*40

32x = 160

Divide by 32

32x/32 = 160/32

x=5

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
