3. Чи проходить графік рівняння х + у = 9 через точку: 1) K(10; –1); 2) F(5;6)?

4. Спростіть вираз:
1) (х – 4)(х + 4) – х(х – 5); 2) (с + 3)2 + (с – 7)(с + 1).
5. Розв’яжіть рівняння 2(х – 5) – 4(х +3) = х – 43. 6. Розв’яжіть систему рівнянь:
7. З пункту А в пункт В вийшов пішохід. Через 1 годину назустріч йому з пункту В виїхав велосипедист. Відстань між пунктами дорівнює 51 км. Відомо, що швидкість велосипедиста на 13 км/год більша за швидкість пішохода. Знайдіть швидкість велосипедиста і швидкість пішохода, якщо до зустрічі пішохід був у дорозі 3 год.

"PROBLEMS THE TEENS FACE" 



Mark: Being  teenagers a complicated and complex experience.
Not only are there mysterious and frightening changes in our bodies, but our
thoughts and feelings are taking on a new direction. Even self-perception is
slowly changing and we start seeing ourselves in a new (and not always
positive) light.We say and do things that we don't want to, or don’t mean to
: cannot tell people around us that we are no longer kids, but we aren't
adults either. We don't know how to control ourselves and focus on the things
that used to interest us: or how to express the waves of emotion building up
inside.And there is a constant overwhelming feeling of being alone and not
understood.: Sometimes even our best friends cannot understand how we feel.There
is no one we can talk to, who can reassure us that what we think and desire it
normal and acceptable. Especially when it comes to sex, there is a deep sense
of guilt, curiosity, and shame that enters our hearts and minds


 

Loran: Everybody says that youth is
the best time of our life, that being young means romance, love, new
discoveries, but it is also the most difficult time, because you have to make
some very important decisions, which will influence all your future life.Things
are not easy nowadays ever, for adults, but for teenagers, who have-to find their
own place in society, it's very difficult. It is necessary not only to adapt to
our society, but also to he confident of your position in 6, 10 or 20 years'
time.For our future it is essential to have a good job. And to get a really
good job you have to be well-educated.Emotional problems for young people can
be very important, as well. The typical teenager problem is that o «nobody
understands me». Some parents often continue to treat their children as little ones
when they probably consider themselves to, be adults.There are some global
problems, facing young people in probably all the countries. Lei's start with
smoking. According to our mass media, at the age of 16 almost 72 % of boys and
37 % of girls in Eastern .Europe have already tried smoking. By the way,
smoking is not a natural demand. Teens start smoking when they want to imitateadults.
Of course, smoking parents practically have no chance to persuade their kids
not to try smoking.Drugs. Students know the names of drugs well enough, some
say they have tried drugs one time, mainly, because of curiosity, friends'
Influence, the wish to relax or to become “cool”.Another problem of youth is
pregnancies among young women. One million teenagers become pregnant each year.
About one million young people run away from home each year. Most of them
return- Those who don't often become criminals.So. you set that problems do
exist and they can't be ignored.
