Find the extrema of f subject to the stated constraint. f(x, y, z) = x − y + z, subject to x2 + y2 + z2 = 7
maximum(x, y, z)= ( )
minimum(x, y, z)= ( )

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

0.02040816326

4

step-by-step explanation:

im pretty sure it's 4 beacsue 8/2 equals 4

is there a question here?
