-3x = 3 + y 3 + y - 5y = -21 -4y = -24 y = 6 x = -3
3
B- It is a many-to-one function
If: 3x = 21 then x = 7
21.
Yes, 3x = 5y is a linear function.
If: 3x-3 = 7x+21 Then: x = -6
-3x=-21+4x-3x-4x=-21+4x-4x-7x=-217x=217x/7=21/7x=3
3x-6=21-6=15
5x2y = 3x - 6y 5x2y + 6y = 3x y(5x2 + 6) = 3x y = (3x)/(5x2 + 6) This is a rational function.
x=-7
3x=96-75 3x=21 x=7
3x = 96 - 75 produces the equations 3x = 21 and x = 7
yes
No.
