Suppose that f(x,y) is a smooth function and that its partial derivatives have the values, fx(−6,7)=−1 and fy(−6,7)=4. Given tha

t f(−6,7)=4, use this information to estimate the value of f(−5,8). Note this is analogous to finding the tangent line approximation to a function of one variable. In fancy terms, it is the first Taylor approximation.

Answer:

7

Step-by-step explanation:

We are given that

f_x(-6,7)=-1

f_y(-6,7)=4

f(-6,7)=4

We have to find the  value of f(-5,8),

We know that

f(x,y)=f(x_0,y_0)+f_x(x_0,y_0)(x-x_0)+f_y(x_0,y_0)(y-y_0)

We have

x=-5,y=8

x_0=-6,y_0=7

f(x,y=f(-6,7)+f_x(-6,7)(x+6)+f_y(-6,7)(y-7)

f(x,y)=4+(-1)(x+6)+4(y-7)

f(x,y)=4-x-6+4y-28=-x+4y-30

f(-5,8)=-(-5)+4(8)-30=5+32-30=7

Solving equations and distributive property
Tomtit [17]

Answer:

x=20

Step-by-step explanation:

2(x+10)=60

distribute 2 by multiplying numbers in parenthesis

2x+20=60

subtract 20 from both sides

2x=40

divide both sides by 2

----------

x=20
