Perpendicular because when you graph it the lines intersect at 90 degree angels.
4 1/2 aka 45/10 use keep change flip and make the problem turn into 9/10 x 5/1 then multiply 9x5 and 10x1 then divide those two numbers.
Answer:
5(n+1)/((n+1)(n+3))
5/(n+3) is a answer
Step-by-step explanation:
(n+1)/(n+1)=1
Answer:
f(3)=1
Step-by-step explanation:
take f(x)=2(x)-5
put a three wherever you see an x in parentheses
f(3)=2(3) - 5
simplify
f(3)=6-5
simplify
f(3)=1
answer:f(3)=1
