Lisa drew a picture of a boat. She used the scale shown.1 inch : 8 feet her picture is 7.25 inches long. What is the length, in feet, of the actual boat? ANS: feet

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

graph of this function as shown below:

the expression (1.26)2t reveals the approximate rate of increases in the number of plants semiannually.

hope this : )

no ,sorry if you needed it but you can ask and try to see if any one will anwser ,

step-by-step explanation:

by good luck mark me as brainliest

have a nice day
