$(x-y)dx + (y+x)dy = 0.$ Show that this is a homogeneous differential equation and hence solve it. You do not need to simplify your answer. Total degree of every term is 1. $\frac{1}{2}ln(\frac{y^2}{x^2}+1) + arctan(\frac{y}{x}) = -lnx + c.$

Texts: 1. Mary is a 22-year-old recent graduate of EMUI. She recently started a new job as a 5th grade teacher, so she is active during the day. She walks her dog very slowly daily for 15 minutes in the morning and 15 minutes in the evening. Mary's daily activities place her in the low active category. She is 55 inches tall and weighs 140 lbs. Use tables from the DRI Summary document to answer the following questions: - What is the DRI EER equation you should use for Mary? EER = 0.11 x weight (kg) + 0.59 x height (cm) - 0.24 x age (years) - 0.03 x physical activity level + 2.03 (for females) - Do you need to convert any of the information provided to be used in the equation? Yes, convert height to cm and weight to kg. Height: 60 inches x 2.54 = 152.4 cm Weight: 140 lbs / 2.2 = 63.5 kg
