Answer:
See below ~
Step-by-step explanation:
We need to represent the situations as inequalities.
===============================================================
<u>Students can work </u><u>no more than</u><u> 23 hours per week</u>
⇒ Let the hours per week be x
⇒ 'no more than' refers to less than or equal to (≤)
⇒ x ≤ 23
=============================================================
<u>Tutors are required to spend </u><u>at least</u><u> 2 hours per week</u>
⇒ At least refers to greater than or equal to (≥)
⇒ x ≥ 2
============================================================
<u>Tutors should spend </u><u>no more than</u><u> 7 hours per week</u>
⇒ As mentioned before, no more than refers to less than or equal to (≤)
⇒ x ≤ 7
Answer:
So if x= 1 , y= -20 , z = -5 , we just have to replace those values on the equation
