Explain why 4xy and 5x²y are not like terms.

1 answer:

3 0

They aren’t like terms became 5x^2y has an exponent

We could have the numbers
5x^2 and 5x and they wouldn’t be like terms because one has an exponent

Which justification describes the process? Step 1. 4x + 2= 10 step 2. 4x=8

blondinia [14]

Answer:

Step-by-step explanation:

The question you have to ask yourself is why did the 2 disappear on the left and why did the 10 decrease in the right.

Whatever you did, you didn't multiply to accomplish that, and you didn't add, both of which would have made things larger.

That leaves B and D. You have to consider D carefully. If you divide, that would make 2 smaller on the left, but it would never make the 2 disappear.

It would also reduce the 10, but the problem is that division would have to effect the x as well.

The answer is that B should be chosen. If you subtract 2 from both sides, the 2 on the left will disappear and you will reduce the 10 to 8 on the right.

I know my answer is a bit convoluted, but I hope it helps.

Which of the following represents the set of possible rational roots for the

yawa3891 [41]

<h3>Answer: Choice D</h3>

The plus/minus of the following: 1/2, 1, 2, 5/2, 4, 5, 10, 20

========================================================

Explanation:

Refer to the rational root theorem. To find the possible rational roots, we divide the factors of the last term 20 over the factors of the first coefficient 2.

Factors of 20 are: 1,2,4,5,10,20
Factors of 2 are: 1,2

Dividing those said factors leads us to the list in choice D. We include the positive and negative versions of each result. For example, divide 10 over 2 to get 10/2 = 5 as one possible root (which leads to -5 as well).

A table like the one shown below might be handy to keep track of all the terms.

Find the common ratio of the geometric sequence.

Kay [80]

Answer:

The common ratio is $\frac{1}{x^4}$

Step-by-step explanation:

Geometric sequence:A geometric sequence is a sequence in which the ratio of any term to the preceding term of that term is always constant.

Common ratio: The ratio of any term to the preceding term of that term.

The $n^{th}$ term of a geometric sequence is represented by $a_n=ar^{n-1}$ .

The $1^{st}$ term of the sequence = a.

The sum of first n term is

$S_n=\frac{a(1-r^n)}{1-r}$

The common ratio = r.

Given geometric sequence,

$\frac{1}{x^{10}}$ , $\frac{1}{x^{14}}$ , $\frac{1}{x^{18}}$ , $\frac{1}{x^{22}}$ ........

The common ratio is

$=\frac{\textrm{second term}}{\textrm{first term}}$

$=\frac{\frac{1}{x^{14}}}{\frac{1}{x^{10}}}$

$=\frac{x^{10}}{x^{14}}$

$=\frac{1}{x^4}$

A tangent contains at most how many chords?

Ivan

<span>This really doesn't make any sense.

A tangent is the slope of a curve at some given point, so it's a straight line. "Chords" don't even apply to straight lines.

The only response that's even in the same galaxy as this weird question is zero.

It's like asking....how many dinosaurs live in the cow pasture?</span><span>
