I feel lucky myself when I was born in a happy family with 4 people. They are my  parents, my younger brother and me. My father is 53 years old. He is as a bread-winner in my family so he has to work hard to feed us. Although he is almost busy all day, he usually spends time to teach me and my younger brother many things in  life. My mother is a farmer. She is 48 years old. She cooks very well. My family to eat whatever she cooks. She always desire to support us in a well-fed family. My younger brother is studying in secondary school. He is tall and  good looking. He is a intelligent student. He is interested in Mathemas and sport. And the last one in family is me. I am a primary teacher. I love my job and students. Their innocent and lovability help me forget the fatigue in life. I will strive to become an excellent teacher and achieve alot achievements in my career. I will try my best to give my parents a more comfortale and happy life. my farther and brother, I to help my mother do the house works. In free time, we sitting together to watch TV and talk about all problems in life. My family is extremely important to me. I love them so much!

Ta có : |y - 2017|\(\ge0\forall y\in R\)

Nên A = |y - 2017| + 2018 \(\ge0+2018\forall y\in R\)

<=>  A = |y - 2017| + 2018 \(\ge2018\forall y\in R\)

Vậy A_min = 2018 khi |y - 2017| = 0 <=>  y - 2017 = 0 <=> y = 2017

GTNN=2018

ta thay vay nha 

|y-2017| phải có giá trị nhỏ nhất mà ta biết giá trị nhỏ nhất của nó là =0

do |y-2017|+2018=0+2018=2018

Donald Trump có 19 cháu, tất cả các lứa tuổi khác nhau. Anna là người lớn tuổi nhất. Tổng số tuổi của lứa tuổi của tất cả các cháu là 190.Am là bao nhiêu tuổi Anna?

trung bình độ tuổi mỗi cháu là:

        190 :19=10 (tuổi)

trong trường hợp đen nhất mà vẫn giữ cho tuổi anna lớn nhất thì phải bớt mỗi cháu đi 1 tuổi.

vậy 18 cháu bớt 1 tuổi thì tuổi của anna là:

            10+18x1=28(tuổi)

                              đ\s:28 tuổi
