If solving for x you will first need to combine like terms. Then after getting the amount of numbers and amount of x numbers you will divide the x number from both. After doing that you would get X=-10
Answer:
i dont know what set a or b is...I would love to help you though...see below.
Step-by-step explanation:
Mean is best used for a data set with numbers that are close together.
The median is the midpoint value of a data set, where the values are arranged in ascending or descending order.
In addition, the standard deviation, like the mean, is normally only appropriate when the continuous data is not significantly skewed or has outliers.
You should use the mode if the data is qualitative (colour etc.) or if quantitative (numbers) with a clearly defined mode (or bi-modal). It is not much use if the distribution is fairly even.
This can be useful if you are measuring a variable that has either a critical low or high threshold (or both) that should not be crossed. The range will instantly inform you whether at least one value broke these critical thresholds. In addition, the range can be used to detect any errors when entering data.
Quantile classification is ideal for ordinal data. When you have a clear ordering of the variables, then this is one of the advantages of quantity classification. If you want to rank data into categories such as high, medium, and low, this is another opportunity to use quantile classification
Hey there! The topic for this problem is Limit of Function!
As for the question, we are given the quadratic function and we have to find the limit, the value that approaches to a.

We call this, "The limit of f(x) when x approaches a."
Then you may ask, "How do we find the limit of function?". That is a very nice question! The answer to your problem is <u>j</u><u>u</u><u>s</u><u>t</u><u> </u><u>s</u><u>u</u><u>b</u><u>s</u><u>t</u><u>i</u><u>t</u><u>u</u><u>t</u><u>e</u><u> </u><u>x</u><u>-</u><u>v</u><u>a</u><u>l</u><u>u</u><u>e</u><u> </u><u>i</u><u>n</u><u>.</u> Although this substitution method only applies when the approaching value doesn't make the denominator to 0. I believe that in the beginning of Limit topic, we learn how to find or evaluate the basic limit that only requires substitution.
So from the question, we receive:

Next step is to <u>s</u><u>u</u><u>b</u><u>s</u><u>t</u><u>i</u><u>t</u><u>u</u><u>t</u><u>e</u><u> </u><u>x</u><u> </u><u>=</u><u> </u><u>2</u> in the function.

Evaluate the value.

Cancel the limit out and there you have it!

Answer
- The limit of quadratic function when x approaches 2 is -3.
Now whenever you learn limit, you must know that limit is when we substitute the <u>a</u><u>p</u><u>p</u><u>r</u><u>o</u><u>a</u><u>c</u><u>h</u><u>i</u><u>n</u><u>g</u><u> </u><u>v</u><u>a</u><u>l</u><u>u</u><u>e</u><u>.</u> That means x —> 2 is not x = 2 but x approaches 2.
Regarding the limit, any questions and doubts can be asked through comment and I will get back to you soon!
Thank you for using Brainly and I hope you have a fantastic day! Good luck on the assignment.
Neither because it touches 0 which is not odd or even.
