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.

Harry ,Louis and Niall Are working with exponents. Harry claims 4^2•4^5=4^10 Louis claims 4^2•4^5=4^7 Niall claims 4^2•4^5=16^7
slavikrds [6]

Answer:

Louis is correct

Step-by-step explanation:

we know that

When multiplying two powers that have the same base, you can add the exponents

so

a^{n} a^{m}=a^{n+m}

so

In this problem we have

4^{2} 4^{5}=4^{2+5}=4^{7}

therefore

Louis is correct

Anestetic [448]

A word problem is used to solve problems in mathematics without the explicit use of equations initially.

<h3>What is a Word Problem?</h3>

This refers to the use of words to generate an equation that can be solved by mathematical means.

Hence, we can see that because the question is incomplete, we can infer that there is a relationship that exists between Dr. White, Dr. Black, Dr. Brown, and a woman that does not have brown hair, and equality would be used to solve it.
