A. Find the linear approximation for the following function at the given point.
b. Use part (a) to estimate the given function value.

f (x, y )= 3x - 4y+ 9xy; (5,6 ); estimate f(4.9,5.99)

a. L(x, y)=
b. L(2.1, -2.91)=

450

step-by-step explanation:

you get texts and minutes, so why not

93.8

step-by-step explanation:

lets say, first number = x

second number = 3x+7

total = 49

(x)+(3x+7)= 49

4x+7 = 49

4x = 42

x = 42/4

x= 10.5

x= 10.5

3x+7 = 3(10.5)+7 = 93.8

hope this

d≈7.07in

step-by-step explanation:

part 1 answer = 8

part 2 answer = 72

step-by-step explanation:

part 1 explanation = add all of the numbers, then divide by how many numbers you have. so, 200/25 = 8.

part 2 explanation = not gonna lie, this is hard to explain, so just google how to do it.
