Prove that ๐ โถ โค โ โค. Let ๐^2 = ๐ โ ๐. Prove that if ๐^2 is injective then f is injective.
Hint: May prove by contradiction, that...
y-5=4x+11
y+4=6x+11
x(x + 2)
17x+14y=-1635
51x+16y=-2721
the equation of a line is y+4=6x+11 what is the value of y at the point where the line crosses the y axis
find c. ab - c = d
find c. ab + c = d
20x+11y=308
