Find the equation of the line that passes through 5,4 and 5,6

2 answers:

Answer: x = 5

Justification:

Realize that this two points are one directly (vertically) over the other.

This is they define a vertical line which is a line parallel to the y-axis.

That means that the line has a constant value of x, I mean the value of x is the same for every y.

The equations of this kind of lines is x = constant, and the constant, as you can notice, is the value of x which is 5 for both points.

So, the answer is x = 5.

As you see, this relation is not a function, because given the value of y you cannot know the value of x (there are infinite y-values that meet the condition x = 5).

Schach [20]

Answer:

You did the same on both exams.

Step-by-step explanation:

To compare both the scores, we need to compute the z scores of both the exams and then compare the values. The formula for z-score is:

Z = (X - μ)/σ

Where X = score obtained

μ = mean score

σ = standard deviation

For Exam 1:

Z = (95 - 79)/8

= 16/8

Z = 2

For Exam 2:

Z = (90 - 60)/15

= 30/15

Z = 2

The z-scores for both the tests are same hence the third option is correct i.e. you did the same on both exams.

Explain why the function of f(x)=4x^2+8x is neither even or odd

myrzilka [38]

Answer:

By putting x = -x in f(x) i.e. f(-x) we didn't get f(x) or -f(x) so, the function is neither even nor odd.

Step-by-step explanation:

We need to explain why the function of $f(x)=4x^2+8x$ is neither even or odd

First we will understand, when the function is even and odd

Even function:

A function is even if f(-x) = f(x)

Odd function:

A function is odd if f(-x) = -f(x)

So, if we get the above result by putting x = -x, then we can say that the function is even or odd.

If we don't get any of the above results then the function is neither even nor odd.

So, for the given function: $f(x)=4x^2+8x$

Put x = -x

$f(x)=4x^2+8x\\Put x=-x\\f(-x)=4(-x)^2+8(-x)\\f(-x)=4x^2-8x$

So, by putting x=-x in f(x) i.e. f(-x) we didn't get f(x) or -f(x) so, the function is neither even nor odd.

Step-by-step explanation:

100 16 45 ÷ 2

50. 8. 45 ÷ 2

25. 4. 45 ÷ 2

25. 2. 45. ÷ 2

25. 1. 45. ÷ 3
