What is when a number decreased by 13, the result is -2?

x - 13 = -2. (bonus: x = 11)

Step-by-step explanation:

hope this helps

Step-by-step explanation:

We can make an equation for this with our unknown number equal to x.

x - 13 = -2

x - 13 + 13 = -2 + 13

x = 11

11 is your answer

good luck!

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
