What is the only solution of 2x2 + 8x = x2 – 16?

2 answers:

8 0

Simplify and solve quadratic equation:

$2x^2+8x=x^2-16 => x^2+8x+16 => (x+4)^2=16 => x={-4,-4}$
So numerically the only solution is x=-4.

However, mathematically, there are two solutions, {-4,-4}, or x=4,multiplicity 2.

What is the mode of the following numbers? 1,2, 10, 6, 4, 4, 6, 3, 1, 4

Answer:

The mode of the data set is 4.

Step-by-step explanation:

Hey there!
The mode of a data set is the most commonly occurring data value in that set.

To begin, we need to organize the data set in increasing order:

1, 1, 2, 3, 4, 4, 4, 6, 6, 10

Then, we can tally the frequency of each data value occurring in the data set:

1 - II

2 - I

3 - I

4 - III

6 - II

10 - I

We can see that there are three occurrences for the data value 4 — which is the most frequent occurrence — so 4 is our answer.
