Answer:
<h2>A) y = -5x - 8</h2>Step-by-step explanation:
The point-slope form of an equation of a line:
m - slope
(x₁, y₁) - point on a line
We have the slope m = -5, and the point (-1, -3). Substitute:
Convert to the slope-intercept form (y = mx + b):
<em>use the distributive property</em>
<em>subtract 3 from both sides</em>
Answer:
The factor form of given expression is (x-4)(x-2i)(x+2i).
Step-by-step explanation:
The given expression is
It can be written as
According to the rational root theorem, all possible rational roots are in the form of
Where, a₀ is constant term and is leading coefficient.
Since the value of f(x) is 0 at x=4, therefore 4 is a root of the function and (x-4) is a factor of given expression.
Use synthetic method to find the remaining factors.
Therefore the factor form of given expression is (x-4)(x-2i)(x+2i).
