For this case, the first thing we must do is define variables.
We have then:

y \geq (x - 3) ^ 2
$
The solution to the system of inequations is given by the shaded region.

x=2
replace the x with 2

2= cucumber plants
10= tomato plants

hope this helps

How to solve this problem

Arisa [49]

$9+ \sqrt{-4}$

Knowing that the square root of a negative number doesn't exist:

$9+ \sqrt{-4}$
$9+2i$ is your answer.

Hope it helped,

Happy homework/ study/ exam!
