Hello the solution system of linear equations

You might be interested in

I’ve worked out that the 1st term is -5 but can’t work out the rest. I thought it was -77 but it’s wrong

Pie

Answer:
1st term: 3(1) - 8 = 3-8= -5
10th term: 3(10) - 8= 30-8= 22
100th term: 3(100)-8= 300-8= 292

Explanation:
Substitute the term number (e.g. 10) in the place of n

Hope this helped! :)

Determine the degree of the term 2^3x2yz4

djyliett [7]

Answer:

Step-by-step explanation:

It looks like the term is $2^3}x^2}yz^4$

First simplify

$8x^2}yz^4$

[y has an exponent of 1 btw]

Then to find the degree of a term, just add up the values of all the exponents

2+1+4=7

I hope this helps!

Perform the indicated operation. Assume that all variables represent non-negative real numbers

Slav-nsk [51]

Without a vale to substitute for the variable, we can only simplify the expression: since $8=4\cdot 2$ and $50 = 25\cdot 2$ , the expression becomes

$-4\sqrt{8m} + 7\sqrt{50m} = -4\sqrt{2\cdot 4m} + 7\sqrt{2\cdot 25m}$

Now use the property $\sqrt{ab} = \sqrt{a}\sqrt{b}\ \forall\ a,b\geq 0$

$-4\sqrt{4}\sqrt{2m} + 7\sqrt{25}\sqrt{2m} = -8\sqrt{2m}+35\sqrt{2m}$

Now we can factor $\sqrt{2m}$ :

$-8\sqrt{2m}+35\sqrt{2m} =\sqrt{2m}(-8+35) = 27\sqrt{2m}$
