Select a counter-example that makes the conclusion false.
Leya [2.2K]

The statement is False.

For this, it is enough to show a case in which the subtraction of two positive numbers is negative.

For this, we must choose two numbers.

Suppose we want to subtract the following numbers:

Number 1: 5

Number 2: 10

Subtracting both numbers we have:

5 - 10 = -5

We observe that the result is negative. Therefore, the given conclusion is false.

Answer:

Counterexample:

5-10 = -5

Which point lies in the solution set for the following system of inequalities?
Sever21 [200]
You can do trial and error to all of the choices. They are presented as coordinates (x,y). Just substitute the x and y values, then if they satisfy the equation, then that is the answer. Among the choices, the answer would be B. Here's why:

x = 3, y = 4

2(3) + 4 > 8
10 > 8   TRUE

3 - 4 < 2
-1 < 2  TRUE

Thus, the answer is B.
