A number x is greater than 7 graph line

Anettt [7]

I graphed this line below.

Start with an open dot on 7.

The reason we use an open dot is because x

does not equal 7, it is only greater than 7.

So from your open dot, draw an arrow to the right

to represent all numbers greater than 7.

Finally, state your answer in set notation if possible.

It is read as {x: x > 7}.

Hi there!

I believe your answer is:

$x = \frac{1}{4}$

»»————-　★　————-««

Here’s why:

⸻⸻⸻⸻

$\boxed{\text{Solving the equation for x...}}\\\\4x + 54 = 55\\----------\\\rightarrow 4x + 54 - 54 = 55 - 54\\\\\rightarrow 4x = 1\\\\\rightarrow \frac{4x=1}{4}\\\\\rightarrow \boxed{x=\frac{1}{4}}$

⸻⸻⸻⸻

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

quester [9]

The difference between $0.20 and $0.60 is: 0.60 - 0.20 = $0.40

The rate of change in 4 years is $0.40
The rate of change in 1 year is $0.10
