Answer:
=> Expand by applying the FOIL method
=> combine like terms
Find slope
(y2-y1)/(x2-x1) is slope
(11-3)/(1-(-1))=8/2=4
y=4x+b
input a point
(1,11)
x=1
y=11
11=4(1)+b
11=4+b
minus 4 from both sides
7=b
the equatin is
y=4x+7
the closest one
minus 4x from both sides
y-4x=7
times everybody by -1
4x-y=-7
last choice is answer
Answer:
4,374
Explanation:
Given the sequence: 2, 6, 18, ...
If we study the pattern we observe that:
This is a geometric sequence with:
• The first term, a=2
,
• Common Ratio, r=3
The nth term of a geometric sequence is obtained using the formula:
Therefore, the 8th term will be:
The 8th term of the sequence is 4,374.
