Evaluate x = -5

1. |4x|

2. |-2 + 5|

For each equation, determine which numbers in {-2, -1, 0, 1, 2} are solutions.

3. |x - 2| = 1

4. |x + 6| = 19

5. 11|x - 9| = 121

6. 5 |x + 4| = 45

I mean, why? Human beings make no sense!! Some other mammels are naked (ie, without fur) but they seem to live underground (naked mole rats) or in the water (dolphins, whales, etc.) Why do we have almost bare skin (except in two places) that burns so easily and is so fragile? Some people believe we also once lived in the water. Does anyone have any ideas?

1. 5(2x - 7) > 10

2. 3(3w+1) > or = to 48

3. 5(5z - 3 ) < or + to 60

4. 40 < or = to -6(5r - 7)

5. 3x + 1 < x + 5

6. 3 - 2x > or = 0

Each clan now has 10 couples of man & woman (20 persons)

Assuming that there is :
10% of zero birth rate
due to infertility, premature death, cancer,
gay/lesbian issues, war/epidemic, etc,

Assuming that there is :
10% divorce/ remarriage
which will also bring babies of the same birth rate.

Clan A: average birth rate 2.5
Clan B: average birth rate 1
Clan C: average birth rate 0.9

After 10 generations,
the total number in clan A = ?
the total number in clan B = ?
the total number in clan C = ?

What method should I use and how to calculate?

And faster way to find out differences between the 3 totals?

Thanks

I remember in science class there was a test we did to test our own blood type. Does anyone know of this test? I know I can ask my doctor but I want to find out about the test cause I thought it was stupid at the time but now I know that it would come in handy.

if aliens/UFOs exist why they don't openly show to us? Why is this still a myth? What is the reason they don't say "you guys we come from this planet, we have this stuff from there, this is how we are ruled, this is what we believe.." and so on.

The drains in our house don't have covers on them and my son was playing with a super bouncy ball in the bathroom and it managed to get in the drain and it has been stuck there ever since. I've had 2 plumbers come and stick a snake in it to push it out but they had no luck. They told me the way the pipes are in our old house that it's stuck and the only way to get it out is to tear out the tub! I don't have that kind of money! So the drain drains REALLY REALLY SLOW. I was thinking I could find something to dissolve the ball entirely. Any chemists out there who know what would make a rubber superball dissolve that would be okay to put down the drain?

What do you think of hydrogen being produced through wind turbines and solar panels? I think it has a long way to go, but shows a lot of promise.

I am considering it, and want to know if you have to be completely dedicated all of the time. I love biology and chemistry, but sometimes I need a break. Does anyone else feel this way, or do I just need to find a new career? I've always wanted to be a doctor.
