Well you know that when you divide you switch the second row to a flip then get the numerator as the denominator.So yeah instead of a divide sign you multiply so yeah.

Which number is not in scientific notation? 0.95 ⋅ 108 1.1 ⋅ 105 7.00 ⋅ 108 9.9 ⋅ 10−28

Answers

$The\ scientific\ notation:a\cdot10^n\ wher\ 1\leq a \ \textless \ 10\ and\ n\in\mathbb{Z}\n\n0.95\cdot10^8-NOT\ because\ 0.95 \ \textless \ 1\n\n1.1\cdot10^5-YES\n\n7.00\cdot10^8-YES\n\n9.9\cdot10^(-28)-YES$

0.95× 10to the power of 8 is not in scientific notation. Scientific notation is when the all but the first number is be hundredths a decimal. So for it to be in scientific notation it would look like this : 9.5×10to the power of 8.

I would think that algebra is. It uses variables. Don't take my word for it, but I'm pretty sure it is that. Hope this helps ^-^

quadratic expressions use variables and they are a branch of math

My algebra math book has this math problem ---> 4a - 3b = 21.i am supposed to figure out if it is true or false. but the thing is, i do not know how to do this so that i can find out if it is true or not.
PLEASE HELP!!!!!

Answers

The value of (4a - 3b) depends on what 'a' and 'b' are.

There are many combinations of 'a' and 'b' that make
(4a - 3b) equal to 21, and a whole bunch of others
that don't.

The equation in your question is not true OR false until you know
what 'a' and 'b' are. I suspect that right next to this problem in your
math book, it gives you some values for 'a' and 'b'.

Here are a few examples of how to do it:

1). I tell you that a=2 and b=1.
You take those numbers, and write them in place
of 'a' and 'b' in the left side of the equation:

   4a - 3b

4(2) - 3(1)

8 - 3 = 5

If a=2 and b=1, then the left side of the equation is 5, not 21,
and the equation is false.

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

2). I tell you that a=5 and b=4.
You take those numbers, and write them in place
of 'a' and 'b' in the left side of the equation:

   4a - 3b

   4(5) - 3(4)

   20 - 12 = 8

If a=5 and b=4, then the left side of the equation is 8, not 21,
and the equation is false.

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

3). I tell you that a=6 and b=1.
You take those numbers, and write them in place
of 'a' and 'b' in the left side of the equation:

   4a - 3b

   4(6) - 3(1)

   24 - 3 = 21

If a=6 and b=1, then the left side of the equation is 21,
and the equation is TRUE.

This is not the only possible pair of numbers for 'a' and 'b'
that make the equation true. There are tons of possibilities.
Look around the question in your book and see if it gives you
values for 'a' and 'b' to test in the equation.
