Answer:
11) 0.6
12) The maximum height of the ball was 2[ seconds] after it was thrown (I am assuming because the answers are cut off a bit.)
13) $2.50
14) (2,-15) 
15) I don't know, since I can't see all the graphs and options. But I want to say the sideways parabola, or the only one shown in the image given
 
        
             
        
        
        
-1 / 7 = x
You need to combine the 2x and 5x then devise the 7x from -1
        
                    
             
        
        
        
Answer:
B. The solution is valid because all steps to solve the inequality for F are correct.
Step-by-step explanation:
F - 32 ≤ 0
Add 32 to both sides of the equation to have;
F -32 + 32 ≤ 0 + 32
F ≤ 0 + 32
F ≤ 32
It can be observed that to solve for F, the steps are correct. Thus the solution is valid. Therefore, the correct choice in the given question is the solution is valid because all steps to solve the inequality for F are correct.
