PLEASE HELP!!! BRAINLIEST IF CORRECT! 40 POINTS

2 answers:

7 0

1. D; -5m+2m, because -5+2=-3

2. B; 4 terms, every part of an expression that's not the subtraction/addition sign counts as a term.

3. Not 100% sure about this one, but I'll go with B; 4x².

4. C; 5b, that term cannot be combined because the variable is different from the rest.

I hope this was helpful.

The five has to be minus, the two is plus. m has to be both. That makes D the answer. The others give 3m 7m and 3m.
Answer D

Two
This question is VERY important. Don;t leave it alone until you understand it.
2x and x can combine. Nothing else can combine with anything else. The answer you get is

3x - 5y + 3

There are 3 different terms. Nothing else will combine because either the letters are different (x and y) or the 3 has no letter with it. This is your answer. Algebra is real picky about that.

Answer A

Three
Another biggy. x^2 is not the same thing as x. The other three will combine by addition. x^2 must be left alone along with 4.
Answer B 4x^2
If you were actually to do this, you would get 9x + 4x^2
Four
5b. the letters are not the same.

Write the power set of the set A={a,b,c}

Burka [1]

Answer:

P(A) = {{a},{b},{c},{a,b},{a,c},{b,c},{a,b,c},∅}

Step-by-step explanation:

➨ Power Set is the set of all subsets.

First, find the subset of A.

{a},{b},{c},{a,b},{a,c},{b,c},{a,b,c},∅

If you aren't sure that you already have written all subsets or not, use the following formula.

$2^n$ ➩ where n is the number of element/members.

Our number of members are 3, use the following formula.

$2^3=8$

Thus, our subsets should be 8.

As we've already gathered all subsets, write the braces all whole subsets.

P(A) = {{a},{b},{c},{a,b},{a,c},{b,c},{a,b,c},∅}

2,10,18,26 find the 61st term

saw5 [17]

Answer:

482

Step-by-step explanation:

We can see that the numbers shown resemble an arithmetic sequence because they have a common difference. The formula for the nth term of an arithmetic sequence is:

$a_{n} =a_{1} +(n-1)d$

Where $a_{1}$ is the first term, $a_{n}$ is the nth term, and $d$ is the common difference. To find the 61st term, all we need is the first term and the common difference. By looking at what given, we can say the first term is 2. Now, to find the common difference, we find the difference of a term from the term before it. In this case we can do $10-2$ , which is $8$ , or the common difference. Since we have everything we need, it can be plugged into the equation:

$a_{61} =2 + (61 - 1)*8\\a_{61} = 2 + 60*8\\a_{61} = 2 + 480\\a_{61} = 482$

So, the 61st term is 482.
