（2）求这两个函数图象与x轴所围成的三角形面积．
18、已知直线y=kx+b经过点A(5，0)，B(1，4)．
(1)求直线AB的解析式；
(2)若直线y=2x-4与直线AB相交于点C，求点C的坐标；

19、已知雅美服装厂现有A种布料70米，B种布料52米，现计划用这两种布料生产M、N两种型号的时装共80套。已知做一套M型号的时装需用A种布料1.1米，B种布料0.4米，可获利50元；做一套N型号的时装需用A种布料0.6米，B种布料0.9米，可获利45元。设生产M型号的时装套数为x，用这批布料生产两种型号的时装所获得的总利润为y元。①求y（元）与x（套）的函数关系式，并求出自变量的取值范围；
②当M型号的时装为多少套时，能使该厂所获利润最大？最大利润是多？
20、快、慢两车分别从相距360千米路程的甲、乙两地同时出发，匀速行驶，先相向而行，快车到达乙地后，停留1小时，然后按原路原速返回，快车比慢车晚1小时到达甲地，快、慢两车距各自出发地的路程y（千米）与出发后所用的时间x（小时）的关系如图所示．
请结合图象信息解答下列问题：
（1）快、慢两车的速度各是多少？
（2）出发多少小时，快、慢两车距各自出发地的路程相等？
（3）直接写出在慢车到达甲地前，快、慢两车相距的路程为150千米的次数．
参考答案：
一、1.C
2.C
3.D
4.D
5.A
6.A
7.C
8.B
二、9.6
10.1
11.不唯一
12.y=1.8x-6(x>10)
13.x=1
y=1
14.-1
三、15、（1）y=3x-5
（2）y=x+
16、解：①当k＞0时，y随x的增大而增大，则有：
当x=-3，y=-5；当x=6时，y=-2，把它们代入y=kx+b中可得
∴
∴函数解析式为y=x-4
②当k<0时则随x的增大而减小，则有：
当x=-3时，y=-2；当x=6时，y=-5，把它们代入y=kx+b中可得
∴
∴函数解析式为y=-x-3
∴函数解析式为y=x-4，或y=-x-3。
17、（1）∵y=x的图象过（2，a），
∴a=1，
∵一次函数y=kx+b的图象经过点（﹣1，﹣5）、（2，1），
∴，解得：．
∴一次函数的解析式为：y=2x﹣3；
（2）一次函数y=2x﹣3交x轴于点（，0），
∴这两个函数图象与x轴所围成的三角形面积为：××1=．
18、（1）∵直线y=kx+b经过点A（5，0），B（1，4），
∴
5k+b=0
k+b=4
，
解得
k=-1
b=5
∴直线AB的解析式为：y=-x+5；
（2）∵若直线y=2x-4与直线AB相交于点C，
∴
y=-x+5
y=2x-4
解得
x=3
y=2
∴点C（3，2）；
（3）根据图象可得x＞3．
19、①y=50x+45（80-x）=5x+3600。
∵两种型号的时装共用A种布料[1.1x+0.6（80-x）]米，
共用B种布料[0.4x+0.9（80-x）]米，
∴
解之得40≤x≤44，
而x为整数，
∴x=40，41，42，43，44，
∴y与x的函数关系式是y=5x+3600（x=40，41，42，43，44）；
②∵y随x的增大而增大，
∴当x=44时，y最大=3820，
即生产M型号的时装44套时，该厂所获利润最大，最大利润是3820元。
20、（1）如图所示：快车一共行驶了7小时，中间停留了1小时，慢车一共行驶了6小时，∵由图可得出两地相距360km，
∴快车速度为：360×2÷6=120（km/h），
慢车速度为：360÷6=60（km/h）；
（2）∵快车速度为：120km/h，
∴360÷120=3（h），
∴A点坐标为；（3，360）
∴B点坐标为（4，360），
可得E点坐标为：（6，360），D点坐标为：（7，0），
∴设BD解析式为：y=kx+b，
4k+b=360
7k+b=0
解得：
k=-120
b=840
∴BD解析式为：y=-120x+840，
设OE解析式为：y=ax，
∴360=6a，
解得：a=60，
∴OE解析式为：y=60x，
当快、慢两车距各自出发地的路程相等时：60x=-120x+840，
解得：x=

Dear
Carlos,Tony
and
I
are
having
a
great
holiday
here
in
Colorado.
The
holidays
are
wonderful.
The
scenery
is
beautiful,and
there
are
many
things
to
do.
of
course
you
can
camp,hike
and
fish.
But
the
best
thing
is
going
down
a
river
on
a
raft(竹筏).
In
the
small
mountain
town
there
is
a
company
that
takes
you
on
the
river.
First,you
ride
in
their
car
for
about
twenty
miles
to
a
special
place
on
the
river.
Then
you
put
the
raft
in
the
water
and
get
in.
a
guide
from
the
company
comes
with
you
to
help
you.
he
tells
you
what
to
do.
the
water
moves
very
fast,and
the
raft
moves
very
quickly.
It
is
a
little
scary(害怕的),but
it
is
a
lot
of
fun.
There
is
a
photographer(摄影师)
who
stands
near
the
river
and
takes
pictures.
How
do
you
think
he
gets
the
film
to
the
store?
He
sends
it
on
the
back
of
a
pigeon(鸽子)!
Really!
He
says
it
is
very
fast,and
the
photographs
are
ready
when
you
finish
your
trip.
We
will
show
you
ours
when
we
get
home.
See
you
soon!

Hiking
is
a
healthy
but
also
a
relaxing
activity.
The
reason

is
a
very
good
exercise
which
will
improve
your
body.
It’s
a
good
exercise
that
doesn’t
hurt
your
body.
Secondly,hiking
is
simple
and
cheap.
All
you
need
to
do
is
to
wear
a
pair
of
hiking
boots
and
your
smile
to
start.
Finally,hiking
is
the
best
way
to
get
away
from
your
everyday
life.
You
could
hike
alone
with
your
friends.
After
hiking,you
will
have
a
clear
mind
and
then
return
to
work
with
confidence
(自信).
So
why
not
plan
your
hiking
route
