Answer:
-$15
Step-by-step explanation:
To find the average yearly change, divide -120 by 8, since it has decreased by $120 over 8 years.
-120/8
= -15
So, the average yearly change in the value of the card is -$15
 
        
                    
             
        
        
        
Hey there! I’m happy to help!
We see that the two equal sides are longer than the base. This means that our a will be larger than b. The problem says that one of the longer sides is 6.3. Since the two longer sides are equal, that means that both longer sides are 6.3 cm. Therefore, we can simply subtract these two from the perimeter to find the shorter side, which is the base. 
15.7-6.3-6.3=3.1
Therefore, the length of the base is 3.1 cm. 
I hope that this helps!
        
             
        
        
        
Answer:
A. -11
Step-by-step explanation:
In the function, replace x with -2
R(x) = x^2 - 3x - 1 ➡ R(-2) = (-2)^2 - 3 × 2 -1 = -11
 
        
             
        
        
        
I am pretty sure the answer is 2,520.
