Interval notation tells you what values where the function is defined. It’s defined all the way from negative infinity to positive 2, then there’s a gap all the way to positive 8, then we continue on to positive infinity. So x, would be literally every single number besides the number between 2 and 8. Oh and don’t forget that brackets mean included, so 2 is also a value that’s acceptable.
x is less than or equal to 2
and
x is greater than 8
Answer:
the third one
Step-by-step explanation:
its easy
The length of XS is 9.
We can get this because of the definition of a bisector. A bisector is something that cuts something else into two equal parts. So, if the something is 18 units long, then half of it would be 9 units. That's exactly what's happening in this problem, so that means that XS, like in our example problem, will be 9.
Answer:
32
Step-by-step explanation:
40 = 100%
how many are 80% ?
well, 80% = 80× 1%
1% = 100% / 100
so, in our case
80% = 80×40/100 = 8×4 = 32
as a shortcut you consider a percentage x as a ratio factor of x/100 you multiply the 100% number with.
in our case
80% = 40 × 80/100 = 32
