Step-by-step explanation:
Geometric Sequence formula for general term:
an = a1(r^n-1)
a1 = 4 × (-5)^1-1
a1 = 4
r = -5
Summation formula for geometric sequence :
Sn = a1 ( 1 - r^n / 1 - r )
...<em>take n from the top of the summation.</em>
= 4 ( 1 -(-5)^6 / 1 -(-5)
= -10416.
Answer:2.81
Step-by-step explanation:
First you subtract the per week (220) from your budget (361)
You get 141
You now divide 141 by 50.15
You come out to 2.81
This means you can drive up to 2.81 miles but no more
Answer:
x=-1/3=10/3 y=-3x+10
Step-by-step explanation:
1. distribute
y+2=-3x+12
2. subtract 2
y=-3x+10
1.subtract 12
y-10=-3x
2. divide by -3
-1/3y+10/3=x
-1, 0.5, 2/3, 1.1 is the order of the numbers from least to greatest
