Answer:
This is a geometry sequence (I.e each term is found by multiplying the same value to the previous term).
T1 = 4
T2 = -12 = T1 X (-3) = 4 X (-3)
T3 = 36 = T2 X (-3) = 4 X (-3)^2
T4 = 108 = T3 X (-3) = 4 X (-3)^3
The general (explicit) formula for the n-th term of this sequence is:
S(n) = 4 X (-3)^(n-1)
Answer:
x=2
Step-by-step explanation:
2*2-x=2
4-x=2 subtract 4 by both sides
-x= -2 multiply each side by -1
x=2 answer
the answer is
d. rational
Step-by-step explanation:
1 gallons is about 3.785 litres.
Hence, the number of gallons in 50 litres is 50/3.785 ≈ 13.2.
The equation is 30,000+200x=80,000. X is the number of sales.
