C=Candy Bar(s)

D=Drink(s)

--------------------

60C+110D=265

120C+90D=270

-------------------

Therefore:

60C=265-110D

Therefore:

2(60C)+90D=270

2(265-110D)+90D=270

530-220D+90D=270

530-270=220D-90D

260=130D

D=260/130

D=2

-------------------

If D=2,

60C=265-110(2)

60C=265-220

60C=45

C=45/60

C=3/4

C=0.75

---------------------

<em>*Candy bars sell for $0.75 whilst drinks sell for $2.00.</em>

Find the tangent plane to the given surface of f(x,y)=6- 6/5 x-y at the point (5, -1, 1). Make sure tat your final answer for th
HACTEHA [7]

Answer:

Required equation of tangent plane is z=\frac{6}{5}(x-5y-11).

Step-by-step explanation:

Given surface function is,

f(x,y)=6-\frac{6}{5}(x-y)

To find tangent plane at the point (5,-1,1).

We know equation of tangent plane at the point $(x_0,y_0,z_0)[/tex] is,

z=f(x_0,y_0)+f_x(x_0,y_0)(x-x_0)+f_y(x_0,y_0)(y-y_0)\hfill (1)

So that,

f(x_0,y_0)=6-\frac{6}{5}(5+1)=-\frac{6}{5}

f_x=-\frac{6}{5}y\implies f_x(5,-1,1)=\frac{6}{5}

f_y=-\frac{6}{5}x\implies f_y(5,-1,1)=-6

Substitute all these values in (1) we get,

z=\frac{6}{5}(x-5)-6(y+1)-\frac{6}{5}

\therefore z=\frac{6}{5}(x-5y-11)

Which is the required euation of tangent plane.
