In triangle ABC, points D and E are the midpoints of and respectively. What are the slope and length of , if the slope and length of are 0.5 and 3.2 units, respectively? A.
slope = -2, length = 3.2 units
B.
slope = 0.25, length = 3.2 units
C.
slope = 0.5, length = 1.6 units
D.
slope = -2, length = 1.6 units
E.
slope = 0.25, length = 1.6 units

answer: $34.31

step-by-step explanation:

$11.99 x 3 = $35.97

$35.97 - 10% = $32.37

$32.37 + 6% = $34.31

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
