Answer:
It is the last answer.
Step-by-step explanation:
If you graph this, there will be no point more negative than (-4/3, -5).
This means the x and y values must be greater than or equal to these values, as the fourth answer will show.

Answer:
The pebble will hit the ground 8.29 second after it is thrown.
Step-by-step explanation:
Given that,
The height of the pebble after t seconds is given by the equation
h= -16t²+24 t+900.
When the pebble hit the ground, the height of the pebble will be zero.
So putting h=0 in the given equation.
0 = -16t²+24 t+900
⇒-4(4t²-6t-225)=0
⇒4t²-6t-225=0
Applying quadratic formula  , here a=4, b= -6 and c= -225.
, here a=4, b= -6 and c= -225.

 ⇒ t = 8.29, -6.79
 Since time can not negative.
∴t=8.29 seconds.
The pebble will hit the ground 8.29 second after it is thrown.
 
        
             
        
        
        
We have that an inverse variation in a function is given by:
 
 We must find the value of the constant k.
 To do this, we substitute the values of x1 = 12, y1 = 15.
 We have then: 

 Clearing k we have: 

 Substituting the value of k we have that the inverse variation is: 

 For y2 = 3 we have: 

 Clearing x2 we have:
