Answer:
70
Step-by-step explanation:
55 + 55 = 110
180 - 110 = 70
The angle is congruent to 70º
A to the middle one
B to the top one
C to the bottom one
The top one is all real numbers because any number in the "l l" absolute brackets will come out to be positive, example: l-3l=3 and l3l=3. Thats going to be equal to and since the sign says "less than or equal to" that will work.
The middle one is only positive solutions because for 7x to be more than lxl it would need to be positive since the sign is "greater than"
The bottom one is none because the absolute of anything will always be more than a negative since the absolute is always positive. Never less or equal to a negative, always more.

The answer is y=5x²
Step-by-step explanation:
If you put y=5x² on a graph paper it will be in a staright line.
Answer:
1320
Step-by-step explanation:
Total number of songs = 12
Number of songs required to arrange in a play list = 3
It means we have to arrange 3 songs from 12 in the play lines. So, required number of ways is
![[\because ^nP_r=\dfrac{n!}{(n-r)!}]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%5EnP_r%3D%5Cdfrac%7Bn%21%7D%7B%28n-r%29%21%7D%5D)
Therefore, the required number of ways is 1320.
Answer:
You're less likely to make mistakes reading or writing very big and very small numbers if you use scientific notation. It also makes it much easier to tell at a glance which numbers are bigger or smaller without counting long strings of zeros.
