Cho ham so y=y (x)=2x-0,3
Tinh f(1) f(-0;2)
Tim 2 so xy bietx/3=y/7va x+y=120 do
\(1-333+3^2-33^3+......+\left(-3\right)^x=\frac{9^{1006}-1}{4}\)
tim x
Tim x,y,z biet
x/2=y/33=z/4 va xy+yz+zx=104
1) Tim x:
\(\frac{1}{2}\cdot x+\frac{3}{5}\cdot x=\frac{-33}{10}\)
Tim x biết y2 = 2x + 33
tim x,y biet
a/ x/y = 3/4 va -3x + 5y =33
b/ x2/y2 = y2/16 va x2 + y2 = 100
c/ x/4 = y/7 va x.y =112
2x = 3y = 5z va x - y + z = -33 . Tim x,y,z
tim x,y biet
a/ x/y = 3/4 va -3x + 5y =33
b/ x2/y2 = y2/16 va x2 + y2 = 100
