(Divide both sides by (-23)/5)
x=2
Step: Substitute2forxiny=−4x+8:
y=−4x+8
y=(−4)(2)+8
y=0(Simplify both sides of the equation)
Answer:
Step-by-step explanation:
Given the geometric sequence
-0.6, 3, -15, 75, ...
Common ratio, 
The next term, 
is obtained by multiplying the previous term c(n-1) by -5.
Therefore, the recursive formula for the sequence is:
Answer:
width = 540
Length = 540 * 4 - 30 = 2,130
Hope that helps! :)
I guess your question is
<span>Sean read 15 of a book in 112 hours. How long will it take Sean to read 12 of this book?
