To answer this, we substitute 12 ft to the f(h) in the given equation,   
 f(h) = -8t² + 8t + 12 = 12
Subtracting 12 from both sides of the equation will give us an answer of,
-8t² + 8t = 0
Then, we transpose 8 to the other side and divide the equation by -8 and t, we get an answer of t = 1 second. 
 
        
                    
             
        
        
        
150 divided by 25 equals 6. 6 times 3 equals 18. This means that you will spend $18 on gas each week. 
        
                    
             
        
        
        
I really hope this helps. I’m sure the answer is c:)

Answer:
The answer is 1
Step-by-step explanation:
Formula for finding the slope: 
Take y2 and y1 from (4,<u>4</u>) (1,<u>1</u>)
Take x2 and x1 from (<u>4</u>,4) (<u>1</u>,1)

This is how the answer is 1
