Ineed writing the equations for these word problems, and maybe an explanation on how to write equations? i have a lot of trouble with it.-1. one angle of a triangle measures 120°. the other two angles are congruent. write and solve an equation to find the measure of the congruent angles.2. linda is paid double her normal hourly rate for each hour she works over 40 hours a week. last week, she worked 52 hours and earned $544. what is her hourly rate?

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:
