Answer:
She would receive 96 points
Step-by-step explanation:
The grade (Y) received on a certain teacher's 100-point test varies in direct proportion to the amount of time(t) a student spends preparing for the test.
Mathematically
Y= kt
Where k is constant of proportionality
If y= 72 and t= 3
72=k3
72/3= k
24= k
So 
Y= 24t
If t= 4
Y= kt
Y= 24(4)
Y= 96
Y = 96 points
She would receive 96 points
 
        
             
        
        
        
Answer:
x=2, y=5
Step-by-step explanation:
PT=TR 
QT=TS
get the system:
y = 2x + 1
3y = 3x + 9
3 * (2x+1) = 3x + 9
6x + 3 = 3x + 9
3x = 6
x = 2
y = 2x + 1 = 2*2 + 1 = 5
