Here is a video of how to do it! https://www.youtube.com/watch?v=c-FVjcPpz54
Answer:
d
Step-by-step explanation:
A(n) = 1 - 0.1(n-1)
A(1) = 1- 0.1*(1-1) = 1 - 0.1*0 = 1
A(2) = 1- 0.1*(2-1) = 1 - 0.1*1 = 1- 0.1 = 0.9
A(3) = 1 - 0.1(3-1) = 1 - 0.1*2 = 1-0.2=0.8
Method:
A(1)=1
D = A(2)-A(1) = 0.9 - 1 = -0.1
A(n) = A(1)+(n-1)*d = 1 + (n-1)*(-0.1)
= 1 - 0.1(n -1)
X = 5 and 2x = 10
the only solution is 5, can be any number
Last one is A, (3,4) and (5,12) because that's where the lines meet therefore it is a solution and this graph consists of two solutions.
