The number of ways you can choose 5 beach towels from a selection of 8 to bring on vacation is a combination problem

<h3>Permutation and combination</h3>

Permutation has to do with arrangement while combination has to do with selection.

When choosing an object from other pool of object, we will have what is called combination.

From the given question, we are told that the number of ways you can choose 5 beach towels from a selection of 8 to bring on vacation, since they are selecting, hence the situation involves combination.

Step-by-step explanation:

2/x + 3 = 1/x

2/x - 1/x = -3

1/x = -3

1 = -3x

x = 1/(-3) = -1/3

the answer would be x=6

to find it you would set 3x-2 equal to 2x+4 and solve because the two sides would be equal if the triangles are congruent

hope this helps :)

Which statement describes how the graph of the given polynomial would change if the term -3x6 is adde

Lesechka [4]

Given:

Polynomial is $2x^6+9x^5-7x^3-1$ .

Term $-3x^6$ is added in the given polynomial.

To find:

The end behavior of new polynomial.

Solution:

Let, $P(x)=2x^6+9x^5-7x^3-1$ .

New polynomial is

$f(x)=2x^6+9x^5-7x^3-1+(-3x^6)$

$f(x)=(2x^6-3x^6)+9x^5-7x^3-1$

$f(x)=-x^6+9x^5-7x^3-1$

Highest power of x is 6 which is even and leading coefficient is negative. So,

$f(x)\to -\infty\text{ as }x\to -\infty$

$f(x)\to -\infty\text{ as }x\to \infty$

Both ends of the graph will approach negative infinity.

Therefore, the correct option is A.
