Answer:
H
Step-by-step explanation:
Find a common denominator. The lowest one would come from you multiplying 2/5 by 4 on each side and 1/4 by 5 on each side. You are left with 8/20 and 5/20, added together would be 13/20.
6+4=10
And Luca’s dad gave 4 treats
Answer:
Sequence :
Rate of change : -3
Step-by-step explanation:
It is given that the sequence represents by the points (1,8), (2,4), (4,1) and (5,0.5).
We know that the represent the point (n,k). So, we have
It is clear that the above sequence is a geometric sequence because it has common ratio .
First term :
Common ratio :
The nth term of a G.P. is
Therefore, the required sequence is .
We need to find the average rate of change from n = 1 to n = 3.
Therefore, the average rate of change from n = 1 to n = 3 is -3.
