Answer: 3
Because X=1
2x1=2
2+1=3
Answer:
d y=4x + 5
Step-by-step explanation:
Is parallel beacause they have the same slope, remember
y=ax + c
where a is the slope of the line
You have to divide both sides by 5 because it states"5t" and you should get "t=20"
Answer:
a(8) = -0.0027
Step-by-step explanation:
The most general formula for a geometric sequence is a(n) = a(1)*r^(n-1), where a(1) is the first term and r is the common ratio.
Here, the formula becomes a(n) = 6*(-1/3)^(n-1).
Substitute 8 for n to find the eighth term:
a(8) = 6*(-1/3)^(8-1), or a(8) = 6(-1/3)^7, or a(8) = -0.0027
72:80
9:10
Divide 72 and 80 by 8 to simplify it and get the ratio
