b is the correct anwser
Step-by-step explanation:
Answer:
The number of complex roots is 6.
Step-by-step explanation:
Descartes's rule of signs tells you that the number of positive real roots is 0. The number of negative real roots will be at most 2. The minimum value of the left side will be between x=0 and x=-1, but will never be negative. Thus all six roots are complex.
_____
The magnitude of x^3 will exceed the magnitude of x^6 only for values of x between -1 and 1. Since the magnitude of either of these terms will not be more than 1 in that range, the left-side expression must be positive everywhere.
<span>Simplifying
8x + -6y = -20
</span><span>Solving
8x + -6y = -20
</span><span>Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right
</span><span>Add '6y' to each side of the equation.
8x + -6y + 6y = -20 + 6y
</span><span>Combine like terms: -6y + 6y = 0
8x + 0 = -20 + 6y
8x = -20 + 6y
</span>
Divide each side by '8'.
x = -2.5 + 0.75y
<span>Simplifying
x = -2.5 + 0.75y</span>
Answer:
Step-by-step explanation:
-the parabola opens downward because a=-3 is negative
-the vertex is at (0, -2)
-axis of symetry is the y-axis so is x=0
-the y-intercept is at (0,-2)
-has imaginary solutions you can find using quadratic formula
