Answer:
In a division algorithm, refers to the dividend polynomial,
refers to the divisor polynomial,
refers to the quotient polynomial and
refers to the residula polynomial.
The division algorithm is defined as
Where and
, other wise the algorithm won't be defined.
So, the complete paragraph is: "if and
are polynomial functions with
and the degree of
is less than or equal to the degree of
, then there exist unique polynomial functions
and
such that
.
For the red line, we have:
gradient (
) = 1/3
y-intercept = 3
Equation of straight line is given by
, where is the gradient and 
is where the line intercept the y-axis
So we have,
The shaded part is above the line, hence the first inequality is
The black line, we have
gradient,
= 3
y-intercept = -2
, rearranging gives
The shaded region is to the right of the line, hence the inequality is
Note: The first option should be the correct answer but the inequality sign for <span>y > 1/3x + 3 should be </span>

Answer:
no solution
Step-by-step explanation:
Given
(21 - 3a) = 6 - a ( multiply through by 3 to clear the fraction )
21 - 3a = 18 - 3a ( subtract 21 from both sides )
- 3a = - 3 - 3a ( add 3a to both sides )
0 = - 3 ← not possible
This indicates the equation has no solution
