4x^2 = 100
x^2 = 25
x = + or - 5
x = 5 or x = -5
Hope this helps.
You just have to do the opposite of what Corey did.
So (18 ÷3 +17) ×2 -25
The answer is 21
Hope I can help you, brainliest answer? :)
You can use the vertical line test to determine if the graph is a function.
A function must: for every x value have only one y value.
Vertical line test: if you draw a bunch of vertical lines each line only touches the graph once.
So a circle would not be a function, or a horizontally facing parabola, etc... Remember, if you draw a vertical line "|" and it touches the graph more than once at any point then it is not a function.
Now take a look at the graph in the question.
In this graph if we do the vertical line test there are no place where a vertical line touches the graph twice so this graph is indeed a function.
This means your answer is C. Yes
Let's turn this sentence into an equation:
8n = -n + 36
Then solve:
9n = 36 => n=4
