Answer: y = -x + 7
Step-by-step explanation:
The slope is
, so we know the equation is of the form
.
Substituting in the coordinates (1,6) to find b,

Thus, the equation is y = -x + 7
I hope this helps you. The answer is c
Bob charges $140
Andy charges $135
Andy is cheaper
The next two numbers are 60 and 600. The pattern is to multiply the number by 10.
Hope that helped.
Answer:
(1)
(2)
If we divide equations (2) and (1) we got:

And then 
And then we can find the value
and we got from equation (1)

And then the general term for the sequence would be given by:

And the best option would be:
C) a1=759,375; an=an−1⋅(1/15)
