Answer:
The required sequence is . The average rate of change from n = 1 to n = 3 is -7.5.
Step-by-step explanation:
From the given graph it is clear that the sequence is a GP because the all terms are half of their previous terms.
Here,
The common ratio of GP is 1/2.
The first term of the sequence is 20.
The formula for sequence is
Where a is first term and r is common difference.
The required sequence is
The formula for rate of change is
The average rate of change from n = 1 to n = 3 is
Therefore the required sequence is . The average rate of change from n = 1 to n = 3 is -7.5.
x+y=0
Step-by-step explanation:
x= 1.75
y= -1.75
Answer:
Step-by-step explanation:
So the first line f(x) is apparently y=3,
g(x) = 1.5x - 2
The x-value at which f(x) = g(x) is
3 = 1.5x - 2
5= 1.5x
x= 10/3 = 3.3333333333333333333

hope that helps!!
Have a wonderful day!!
B. y= -3x - 2
you go down twice hence the -
