You are given a feasible region. find the maximum and minimum (if they exist) for the given objective function. (if an answer does not exist, enter dne.) z = 18x + 30y

the thermometer is precise but not accurate

step-by-step explanation:

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)

thats not a system of equations, that is a solution

if you are looking for the unit rate then the answer would be 9 because unit rate is distance divided by time.
