According to the table given, the rate of change is of 9.
The <em>rate of change</em> is given by the <u>change in the output divided by the change in the input.</u>
In this problem:
- The input is the number of bouquets.
- The output is the number of flowers.
Taking two of the points, (3,27) and (5,45), we have that:

Hence, the rate of change is of 9, which would be verified taking any pair of two points.

x = 5
y = -1
Step-by-step explanation:
from second equation,
by putting the value of y in first equation
- y = -x + 4
- -1 = -x + 4
- -x = -1 -4
- -x = -5
- x = 5
x = 5 and y = -1
The correct proportions are given as follows:
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three.
The proportions for this problem are given dividing y by x, hence:
- x = 3, y = 27: 27/3 = 9, hence 9/1 has to be marked.
- x = 9, y = 81: 81/9 = 9, hence 9/1 has to be marked.
- x = 21, y = 126: 126/6 = 6, hence 6/1 has to be marked.
- x = 14, y = 84: 84/14 = 6, hence 6/1 has to be marked.
- x = 12, y = 36: 36/12 = 3, hence 3/1 has to be marked.
- x = 15, y = 45: 45/15 = 3, hence 3/1 has to be marked.

Answer:
n=5 and it's output is -13
Step-by-step explanation:
By inspection, the inputs increase by +1 and the outputs decrease by 2
Thus ,n=4+1=5 and it's output is -11-2=-13
