In math formulas, A and a, always represent the same number.

 False

Step-by-step explanation:

In math formulas, we want to use different symbols to represent different things.

While in linguistics, A and a represent the same thing, the symbols are different, then we can use them to represent different things.

For example, we can define a square of side length a.

And the area of that square will be equal to the square of its side length, we can represent the area with A, such that:

A = a^2.

Here A and a are different numbers (and also represent different measures, a is in units of length and A is in units of surface).

Then the statement is false.

choice b is correct

step-by-step explanation:

we have been given the following system of inequalities;

we are required to graph the solution to the system of inequalities. using a graphing tool, the graph of the system is as shown in the attachment. the continuous line represents the graph of while the dotted line represents .
