Answer:
The zeros of f(x) are: (x - 1), (x - 3) and (x - 8)
<em></em>
Step-by-step explanation:
Given


Required
Find all zeros of the f(x)
If
then:

And
is a factor
Divide f(x) by x - 8

Expand the numerator

Rewrite as:

Factorize

Expand

Factorize


Multiply both sides by x - 8

<em>Hence, the zeros of f(x) are: (x - 1), (x - 3) and (x - 8)</em>

Answers A. and B. Are correct
Answer:
∠x = 59°
Step-by-step explanation:
∠ECD = 52° because they are alternate angles and will be equal
∠x = 180° - 52° - 69° = 59° because the sum of the interior angles of a triangle = 180°
Answer:
y ≥ 3x -1; x +3y ≤ 6
Step-by-step explanation:
Both lines are solid, so the only viable choices are those with "or equal to" in the comparison operators: the 2nd and 4th choices.
The line with a slope of +3 is shaded <u><em>above</em></u> the line, so that will correspond to the inequality ...
y ≥ 3x -1 . . . . . . . . . . found only in the 4th choice.
