There are multiple ways to do this.
The easiest is to just continuously subtract 7 from 65 the numbers of times needed.
But most math teachers will have you use the equation ar^n-1 where a= the first term (65), r=ratio (-7), and n=the term you need (second, fifth, and ninth).
So to solve you just plug your values in as so
AR^n-1
(65)(-7)^2-1(65)(-7)^5-1
(65)(-7)^9-1
Answer: 10
Step-by-step explanation: Combine like terms for y, so add then you get 10.
Answer:
1. Perpendicular
2. y=5x+7
Step-by-step explanation:
brainliest please?
Y=x-3 it's one of many equations
80 inches or feet.. I think you are suppose to multiply 40x2 sorry if im wrong
