y = (11-4x)/5
x=2.75 This follows from the equation (4x - 3) + 11 = 19 and 4x = 11
X=1/2
7
(2x + 1)(2x + 1) or (2x + 1)2 so x = -0.5
x = -½
y=xsquared-4x+2
The discriminant is 121.
x2-10 = 4x+11 x2-4x-10-11 = 0 x2-4x-21 = 0 (x+3)(x-7) = 0 x = -3 and x = 7
y = (11-4x)/5
Y = x squared -4x plus 3 is an equation of a function. It is neither called a domain nor a range.
-11
= 3
x=2.75 This follows from the equation (4x - 3) + 11 = 19 and 4x = 11
X=1/2
It equals 53X- a number is squared when it is multiplied by itself, so 7X by 7X = 49X. 2X by 2X =4X, so 49X + 4X is 53X.
