Answer:
1
Step-by-step explanation:
Take any two points from the line:
I will take (-1,0) (0,1)
slope formula:
m = y2 - y1 / x2 - x1
m = 1 - 0 / 0 - (-1)
m = 1 / 0 + 1
m = 1 / 1
m = 1

Answer:
-2b/(a-b)
Step-by-step explanation:
1− (a+b/a−b)
We need to get a common denominator of a-b
1 = (a-b)/(a-b)
Replace 1 with (a-b)/(a-b)
(a-b)/(a-b) - (a+b)/(a-b)
Put over the common denominator
(a-b) - (a+b)
-----------------
(a-b)
Distribute the minus sign.
(a-b) - a-b)
-----------------
(a-b)
a-a-b-b
---------------
a-b
-2b
----------
a-b
We open the brackets
And use the laws of indices
-2x^2(-5X^2+4X^3)
Opening brackets
10X^4-8X^5 we get X^4 and X^5 because the terms we have
multiplied have common bases and therefore we have added the powers
Hence our answer is 10X^4-8X^5

Hi!
This question is worded a little funny, but i think in understand what it's asking. Forgive me if i'm wrong.
Place values in math are pretty self-explanatory. It's just asking you what place each number is in.
For example:
If you were to write the number 12, the 1 would be in the tens place and the 2 would be in the ones place.
When speaking about decimals, you pretty much just have to add the letters 'th' to the end of the place value, but instead of decreasing as the numbers grow smaller, you increase and the ones place doesn't exist.
So in this case:
With 249.637, 2 is in the hundreds place. 4 is in the tens place. 9 is in the ones place. 6 is in the tenths place. 7 is in the hundreths place. 3 is in the thousandths place.
Hope this helps :)
I had to read this about 5 times in order to understand what it was asking xD!!
It's just asking "how many times do you multiply 10 to get 10^12, divide that by 2, then multiply that by 10".
12 divided by 2 multiplied by 10
6 multiplied by 10
60 dB
I'm not positive, but I believe it's 60 dB
