Y = 10x 10x = 40 y = 40
the number 1 is the only solution. y-1 = 0 1-1 = 0 every single number except 1 is not a solution your domian would equal D=All Reals (such that y is not equal to 1)
-273
135
That would be Y2 or Y squared.
y = -5x2 - x + 9
If you mean: y = 6x+4 then the slope is 6 and the y intercept is 4
15
It is an algebraic expression in the two variables, x and y.
If you mean: y = 6x+4 then it is a straight line equation with a slope of 6 and a y intercept of 4
If you mean: y = 6x+11 and y = 2x+7 Then by substitution: x = -1 and y = 5
if you mean y=6x then y is the same as 6 times x if x means 3.5 then y is six times 3.5 if you can't do multiplying, add them up ! (its 21)
If you mean: y = 6x+2 then its perpendicular line is -1/6.

y = 6x2 + x -1 ?? discriminant = b2 - 4ac = 12 - 4(6)(-1) = 25
y = 15 (by transitivity)
8 + y = 7 + 5y <----they are equal to the same number so are equal to each other 4y = 1 y = 0.25
