Answer:
x + y < 20
5x + 10y ≥ 100
Step-by-step explanation:
The ski club wants at least $100
Student pays $5
Chaperone pays $10
Maximum number of seats = 20
Assumption:
Assumed number of students = x
Assumed number of chaperone = y
Equation:
Maximum number of seats = 20
⇒ x + y < 20
The club wants $100
⇒ 5x + 10y ≥ 100
Definately option C
- As it's mentioned y=x+4 it must be function
- So in function every domain has its unique range.
- Hence here the slope is not constant
As
The graph shown is a parabola which is not y=x+4
So option C is wrong
Practice, practice & practice.
