Combine like terms to simplify the expression. 5x + 4 + 2x + 5

7x+9

Step-by-step explanation:

Add the numbers

5x + 4 + 2x + 5

5x+9+2x

Combine like terms

5x+9+2x

7x+9

Solution:

7x+9

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

the answer is somewhere there guys it really . there im just not gonna answer

but i'm guessing ur first option tho
