Answer:
The answer is B y = 1.5x – 4.5
Step-by-step explanation:
The level of each growth factor is an illustration of a combination
There are 90 ways of combining one level from each growth factors
<h3>How to determine the
number of combinations?</h3>
From the complete question (see attachment), we have the number of levels in each growth factor is:
Lighting = 3
Age = 5
Temperature = 2
Humidity = 3
So, the number of combination (n) is:
n = 3 * 5 * 2 * 3
n = 90
Hence, there are 90 ways of combining one level from each growth factor.

4. all for angles need to equal 360
90 +90 + 42 = 222
360-222 = 138
y = 138 degrees
x - 42 degrees
6. x = arctan(8/4) = 63.43 degrees ( round as needed)
y = 16 / tan(63) = 8.15 ( round as needed)
we have that
we know that
If two lines are parallel
then
their slopes are equals
and
if two lines are perpendicular
then
the product of their slopes is equal to 
step 1
find the slope of the line segment AB
step 2
find the slope of the line segment CD
therefore
the answer is
Line segments AB and CD are perpendicular
One of the easier ways of simplifying 0.25/0.75 would be to recognice that 0.25 goes into 0.75 3 times. Thus, 0.25/0.75 = 1/3.
Similary, 6.25/12.5 = 6.25/12.50 = 1/2.
