=>Điểm A(1000000,4000000) thuộc đồ thị hàm số y=4x
Đặt x=1000000=>y=4x1000000=4000000
=>Điểm A(1000000,4000000) thuộc đồ thị hàm số y=4x
ve do thi y=3.x-4 ve 1 doan thang tu x=1 den x=3
y=(2.x+m)+1 tim m sao cho do thi cat truc tung tai 5
2.(4x-3)^2=|3-4x|

Các ban giải nhanh mình đang ôn thi
cho hai duong thang ab va cd cat nhau tai i tao thanh goc aic co so do 35
a. tinh so do cua hai goc bid va goc aid

So sánh A=\(\left(ax+by\right)^2\)và B=\(\left(a^2+b^2\right)\left(x^2+y^2\right)\) biết rằng a=2,b=-1;x=\(\dfrac{8}{11}\):y=\(-\dfrac{5}{11}\)
cho don thuc A=19/5 xy^2(x^3y)(-3x^13y^5)^0
a, thu gon don thuc A
b, tim he so va bac cua don thuc
c, tinh gia tri cua don thuc tai x=1, y=2
a, cho tam giac ABC va tam giac A\(_1\)B\(_1\)C\(_1\) co AB=A\(_1\)B\(_1\). AC=A\(_1\)C\(_1\) va BC> B\(_1\)C\(_1\). So sanh so do cua 2 goc A va A\(_1\)
b,cho tam giac ABC va tam giac A\(_1\)B\(_1\)C\(_1\) co AB=A\(_1\)B\(_1\). AC=A\(_1\)C\(_1\) va A>A\(_1\).chung minh rang BC>B\(_1\)C\(_1\)
a, cho tam giac ABC va tam giac A\(_1\)B\(_1\)C\(_1\) co AB=A\(_1\)B\(_1\), AC=A\(_1\)C\(_1\) va BC > B\(_1\)C\(_1\). So sanh so do cua 2 goc A va A\(_1\)
b, cho 2 tam giac ABC va A\(_1\)B\(_1\)C\(_1\) co AB=A\(_1\)B\(_1\), AC=A\(_1\)C\(_1\) va A >A\(_1\).Chung minh rang BC > B\(_1\)C\(_1\)
