Answer:
Average rate of change = 3 
Step-by-step explanation:
- We know that the average rate of change is basically a measure of the slope of the  secant line  in the closed interval [a, b].
here   a = -3 and b = 4
⇒ Average rate of change = f(b) - f(a)  / b - a
                                             = (27 - 6) / (4 - (-3))
                                             = 21 / 7
                                             = 3
Therefore, Average rate of change = 3 
 
        
             
        
        
        
Answer:
B
Step-by-step explanation:
According to the theorem, equal sides have equal angles opposite to them so AB AND AC are equal so x and y are also equal
 
        
             
        
        
        
Answer:
15
Step-by-step explanation:
1 dime = 10
1 quarter=25
x=number of coins - dimes
y= number of coins - quarters
x (10)+y(25)=10.25
x+y=50
x= 50-y
x(10)+y(25)=1025
(50-y)(10)+25y =1025
500-10y+25y=1025
500+15y=1025
15y= 1025 - 500
15y=525
y=525/15
y=35
x= 50-35=15
 
        
             
        
        
        
Answer:
A
Step-by-step explanation: I believe it's A because It's the opposite but I'm not 100% certain, because I don't remember inverse statements.
