I will give Brainiest if you are right

The answer is F!

Step-by-step explanation:

The dot starts at 7 with the arrow going towards the left.

Seeing how 15 on the right side (of all inquealities) is positive, that means if we subtract both sides from positive 8, we will get positive 7 on the right side.

So we want the variable x to be equal to 7 or less than 7.

ELIMINATE choice F.

ELIMINATE choice H & J.

in mathematics, a function is a relationship between two variables such that the value of one of the variables, called the dependent variable, is determined by the value of the other variable, called the independent variable. there is a specific term we use to describe the set of independent variables of a function.
