The answer is the second options
Answer:
(x+2, y-6)
answer C
Step-by-step explanation:
Y=5x+30
X is the days
And so by plugging in x you get
y=5(5)+30
y=25+30
y=55
And so by day 5 she's running 55 minutes
But that's what I think
1) factor the denominators: 2b/(b-1)2 - 2/ (b-1)2
2) MAKE SURE YOU HAVE A COMMON DENOMINATOR
3) combine the numerators: 2b-2/(b-1)2
4) distribute 2 from numerator: 2(b-1)/(b-1)2
5) simplify; answer is 2/(b-1)
