Does anyone know -6/7+6/21

1 answer:

4 0

Simple...

you have: $-\frac{6}{7} + \frac{6}{21}$

You must find a common denominator first-->>

$- \frac{6}{7} * \frac{3}{3} = -\frac{18}{21}$

Now...

$- \frac{18}{21} + \frac{6}{21} = -\frac{12}{21}$

$= -\frac{12}{21}$

Simplify it-->> $-\frac{4}{7}$

Thus, your answer.

The answer is A. The angles are congruent, meaning 6x+1= 49. Using basic algebra, 6x=48, leaving you with X=8.

Describe the end behavior of f(x)=-2x^3 using the leading coefficient and degree, and state the domain and range

astra-53 [7]

Answer:

See explanation for end behavior below

Domain = All Real numbers

Range = All Real numbers

Step-by-step explanation:

This is a typical power function of order 3, and since its coefficient is a negative one (-2), its end behavior is:

As x becomes more and more negative (moving towards the left of the horizontal axis, the values for y will become larger and larger (reaching very positive numbers on the y scale). As x becomes larger and larger (moving towards large values on the positive side of the horizontal axis, the related y values will become more and more negative.

The Domain of the function (the x-values for which the function is defined) consists of all Real numbers.

The same is true for the Range, since the y-values spread over all the real number line.
