The coefficients of the polynomial are rational, which means that any non-real roots occur alongside their complex conjugates. In this case, 6+<em>i</em> is a root, so 6-<em>i</em> is also a root.
So the simplest polynomial you can build with these roots is
(<em>x</em> - (-5)) (<em>x</em> - (6 + <em>i </em>)) (<em>x</em> - (6 - <em>i</em> )) = <em>x</em> ^3 - 7<em>x</em> ^2 - 23<em>x</em> + 185

Answer:
y = -4x - 22
Step-by-step explanation:
m = -4
using (-6,2)
Slope-intercept: y = mx + b
2 = -4(-6) + b
2 = 24 + b
b = -22
y = -4x - 22
Answer:
21.C
23.B
24.D
Step-by-step explanation:
Domain is x
Range is y
If you can find a relation between x and y, that relation is a function.
In 21,
I. y = 0.x +5
II. Nothing.
III. y = x
In 22,
15 birdhouses needed to be built, then domain is from 0 - 15
In 23,
Try to insert x in to f(x) you will find out f(x), for i.e : x = 0, f(x) = 0.10 x 0 +5 =5.
