Answer:
The answer would be -9
Step-by-step explanation:
-(3)^2
-(9)
-9
Following order of operations (PEMDAS)
 
        
             
        
        
        
Answer:
The average slope is 8.
Step-by-step explanation:
Let <em>f</em> be defined on the closed interval [a, b]. The average slope of <em>f </em>between a and b is the quotient
                                        average slope = 
To find the average slope of the function  on the interval [-1, 3] you have to evaluate your function in the interval and then divide by the interval.
 on the interval [-1, 3] you have to evaluate your function in the interval and then divide by the interval.
So,

The average slope is  
 
        
             
        
        
        
you would do PEMDAS 
you do -3 times 4. then you do that and devide by -3.

Answer:
Ram studied for longer time
Step-by-step explanation:
An hour = 60 minutes
Raj studied for 4/7 of an hour
= 4/7 of 60 minutes
= 4/7 × 60
= (4×60)/7
= 240/7
= 24.29 minutes
ram studied for 5/8 of an hour
= 5/8 of 60 minutes
= 5/8 × 60
= (5×60)/8
= 300/8
= 37.5 minutes
who studied for longer time?
Ram - Raj
= 37.5 - 24.29
= 13.21 minutes
Ram studied for longer time
Ram studied 13.21 minutes longer than Raj
