Question A. Find the domain for the given functions.. 1) f(x, y) =1/x + y

2) f(x, y) = 3xy/y – x^2

Question B. Find the range for the given function.

1) f(x, y) = e^x-y

2) lim
(x, y)--(0,0)
=x(cos y - 1)/x^3 + y^2

Evaluate the limit.

answer

106 emergencies

step-by-step explanation:

41*67/2=1373.5

step-by-step explanation:

i just used a calculator

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

5+2x=a
