6. Rectangle A measures 12 cm by 16 cm. Rectangle B is a scaled copy of Rectangle A.
a) If the scale factor is, what are the c) If Rectangle B has dimensions of 12
dimensions of Rectangle B?
in. by 16 in., what is the scale factor?
b) If the scale factor is 3, what are the
dimensions of Rectangle B?
d) If Rectangle B has dimensions of 18
in. by 24 in., what is the scale factor?

step-by-step explanation:

9-15%

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation

step-by-step explanation:

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
