HELP!!!! 3. Find the x-intercept of the graph of the linear equation y = 2x + 4.

Naily [24]

Hi there!

»»————-　★　————-««

I believe your answer is:

(-2, 0)

»»————-　★　————-««

Here’s why:

⸻⸻⸻⸻

$\text{Substitute in \textbf{0} for } y \text{ and solve for } x\text{.}\\-------------------\\y = 2x+4\\-------------------\\\rightarrow 0 = 2x +4\\\\\rightarrow 2x + 4 = 0\\\\\rightarrow 2x +4 - 4 = 0 - 4\\\\\rightarrow 2x = -4\\\\\rightarrow\frac{2x=-4}{2}\\\\\rightarrow \boxed{x=-2}$

⸻⸻⸻⸻

$\text{The \textbf{x-intercept} of the given equation is: } (-2, 0)$

⸻⸻⸻⸻

Hope this helps you. I apologize if it’s incorrect.

Is Integer a Rational Number?

slava [35]

Hey there!

Before we get to know an Integer and Rational Number, we have to know the Real Number system first.

1. What is Real Number System?

Real Number System is very commonly used in mathematics. It is a number system that is "logical", at least when it comes to solving an equation.

But do you know that the Real Number system can be broken into two categorizes? And what are them?

Real Numbers can be broken into these main two categorizes which are:

Irrational Number
Rational Number

These numbers can also be broken into other categorizes as well! Crazy, ain't it? Well that's how maths work!

Anyways, we will skip Irrational Number since it is off-topic and not related to your question. We will talk about Rational Number instead.

2. What is Rational Number?

Rational Number is a number that can be written in fraction form. That is a simple explanation for the Rational Number. Please lecture or note that approximations aren't considered as rational numbers. Even though π ≈ 22/7 which is in fraction form but it is just an approximation which is considered as Irrational Number. Also if infinity/endless decimal can be written in fraction form as well, they are considered as Rational Number too!

Now we know the meaning of Rational Number. But like I said, the Rational Number can be broken into other categorizes which are:

Integers - Whole number or number without fraction or decimal.
Fractions and Decimals that can be written in fraction form.

And Integers can also be broken into:

Negative Integers
Zero
Positive Integers

3. Conclusion and Answer

Since Integers are subset of Rational Number, we can conclude that Integers are Rational Number.

Hope this helps, and let me know if you have any doubts regarding Real Number system.

Help,anyone can help me do quetion,I will mark brainlest.

maks197457 [2]

180m

To find this we need to find the perimeter. The perimeter is not given so we need to find it. If the land is square we can assume all sides are the same length. So to find the perimeter we need to find the side length. So we find the square root of the volume. The square root of 2025 is 45. So we now add all the side lengths together. The equation is 45+45+45+45. This makes 180m. It takes 180m of fence.

Hope this helps. Please consider making me the Brainliest, it’s not necessary but it is appreciated as I put time and research into each answer. Have a great day, stay safe and stay healthy.
