Since
you can see that common expression is
.
Answer: Correct choice is A.
Answer:
y = (½)x
Step-by-step explanation:
(-8,-4) (0,0) and (8,4)
Use any 2 points to find the slope, hence the equation
slope = (y2-y1)/(x2-x1)
= (0-(-4))/(0-(-8))
= 4/8
= ½
y = (½)x + c
When x=0, y=0
0 = (½)(0) + c
c = 0
Equation is:
y = (½)x
The common difference is 19-7 = 31-19 = 12, so this is an arithmetic sequence. The initial term (when n=1) is 7.
The explicit formula for the terms of an arithmetic sequence is
an = a1 + d(n-1)
where "a1" is the first term and "d" is the common difference. The formula that matches a1=7 and d=12 is
B. a(n) = 7+(n-1)·12
9% decrease because 145-132=13
13=9% of 145
