Since 1 cm = 10 mm
Then 4 cm = 40 mm
Answer:

Step-by-step explanation:
we have

Remember that
To predict a value for y, when x = 4
substitute the value of x in the equation
so

Answer:
For product A, the product is increasing, for the bigger the number you plug into x (due to the fact that the numbers become bigger because of the time: year 1, year 2, etc)
Product A is 82% change rate, while
product B is 983.45/4 = 245.8625, 1756.16/3 = 585.3867
Product B is 245.8625/585.3867
product B is 42% change rate
Product A change rate is higher than Product B by 40%

Answer: See Annex
z (max) = 190
x = 10
y = 20
Step-by-step explanation:
z = 5*x + 7*y to maximize
Subject to:
x + y ≤ 30
2*x + y ≤50
2*x - y ≥ 0
x≥= y ≥0
