Answer:
9
Step-by-step explanation:
Let the no be x
By the conditions given ,
2x + 6x = 72
8x = 72
x = 72/8
x = 9
therefore the no is 9
3 * 100 = 300 because it is only asking you to claculate 3*100
The functions could represent g(x) is B. 
<h3>How can the function be determined?</h3>
Using the general equation 
The g(x) has intercept of y=-2,
Then the y-intercept of f(x) is at y=3
If we find the difference between both y-intercepts, we have
( -2 -3) = -5
Then b=-5
Hence,
is correct.

Answer:

Step-by-step explanation:
Complex numbers:
The following relation is important for complex numbers:

Zeros of a function:
Given a polynomial f(x), this polynomial has roots
such that it can be written as:
, in which a is the leading coefficient.
Has zeros −19 and −i
If -i is a zero, its conjugate i is also a zero. So

Output of 40 when x=1
This means that when
. We use this to find the leading coefficient a. So




The polynomial is:
