3x+1/10=x-1/7 subtract 1/10 from both sides 3x=-1/7-1/10+x subtract x from both sides 2x=-1/7-1/10 add -1/7 and -1/0 1/7=10/70 1/10=7/70 -10/70-7/70=-17/70 2x=-17/70 divide by 2 ro multiply by 1/2 x=-17/140

Find the absolute minimum and absolute maximum of f(x,y)=14−7x+10y f(x,y)=14−7x+10y on the closed triangular region with vertice

Black_prince [1.1K]

Answer:

Maximum value of f(x,y) at (10,13)=74

Minimum value of f(x,y) at (10,0)=-56

Step-by-step explanation:

We are given that

$f(x,y)=14-7x+10y$

Vertices are (0,0),(10,0) and (10,13)

Substitute x=0 and y=0

$f(0,0)=14-0+0=14$

Substitute x=10 and y=0

$f(10,0)=14-7(10)+10(0)=14-70=-56$

Substitute x=10 and y=13

$f(10,13)=14-7(10)+10(13)=14-70+130=74$

Maximum value of f(x,y) at (10,13)=74

Minimum value of f(x,y) at (10,0)=-56
