y = -4x2 - 16x - 11
you can try to factor it or use the quadratic formula:
x = (-b + (b2-4ac)1/2)/(2a)
x = (-b - (b2-4ac)1/2)/(2a)
so...
x = (16 +/- (162- (4*-4*-11))1/2)/(2*-4)
x = (16 +/- (80)1/2)/-8
in decimals, you have:
x = (16+8.944)/-8 = -3.118
x = (16-8.944)/-8 = -0.882

What algebraic property is 8 equals x and x equals y?
Transitive property: If 8 equals x and x equals y, then 8 equals y.
If y Varies Directly as x to the 2nd power and y equals 198 when x equals 6 find y when x equals 2?
y=kx^2 hence k=198/36. now y=198/36*(2)^2 y=22
Is it possible to solve y equals 4Xto the power of 4 plus 2Xto the power of 2 plus 3?
Not if you want REAL solutions: y=4x^4 +2x^2 +3 t=x^2 therefore y=4t^2 +2t +3 Use discriminant: b^2-4ac=4-48=-44 this means there will be no REAL solutions (but there will be COMPLEX solutions-message me if you need this bit explained)
If 3 plus y equals a 3-y equals a then a equals y equals?

What does y equals 9x equals 3 equal?
y=9x=3it equals ......y= 3.334
What is the answer for y equals x?
x equals y
If y equals 6x and x equals 1.5 what is y?
y=9
What is the y intercept for y equals -2x?
The y-intercept equals 0.
What does y plus y equals?
-17 + y,,must be equals to..-17y..
Given y equals 3x plus 1 and x equals 3 then y equals?
y=10
If y equals one-forth x and x equals -12 then what is y?
x equals -12 and y equals 1/4 of -12, so y = -3.
