B) Sharon lost 8 pounds and then gained 10 pounds.
A) 12-12=0
B) -8+10=2
C) Profit=Income-Expenses
D) 5-5=0
We know that if K is between H and J that HK+KJ=HJ therefore by substitution, x-5+5x-12=25
6x-17=25
6x=42
x=7
First one.
tan(pi/2) is the asymptote, and 2pi/4*x = pi/2*x, between 0<x<2, goes from 0 to pi, so it only passes thru pi/2.
FIRST one
