Common ratio, r = (-125)/625 = -0.2
First term, a = 625
7 term
= ar^6
= 625(-0.2)^6
= -0.04
Answer:
-10 is not a solution to the equation
Step-by-step explanation:
I don't really have an explanation
The points (1,-2) and (4,16) are not in the line but the point (-3,-18) is on the line. (Work is shown in the image)
Additive inverses combine to get 0. So, k is -1.4. The sum is 0. Hopefully that will help.
