Consider the function represented by 9x + 3y = 12 with x as the independent variable. How can this function be written using fun

aivan3 [116]

"-3f(x) means ""the function of x"" and is another way of writing y when the variable x is an independent variable. To get f(x) on one side of the equation, do the following:9x + 3y - 9x = 12 - 9x3y = 12 - 9x3y / 3 = (12 - 9x) / 3y = 12/3 - 9x/3y = 4 - 3xy = f(x) = -3x + 4"

A rectangular box with an open top has a length of x feet, a width of y feet, and a height of z feet. It costs $4.20 per square

daser333 [38]

Answer:

$C(x,y,z) = 4.2xy + 1.5xz + 1.5yz$

Step-by-step explanation:

We are given the following information in the question:

A rectangular box has a length of x feet, a width of y feet, and a height of z feet.

Area of base =

$\text{Length}\times \text{Base}\\=x\times y$

Cost of building base = $4.20 per square foot

Total cost of building base =

$\text{Area of base}\times 4.20\\= 4.2xy$

Area of 4 walls =

$2(\text{Length}\times \text{Height} + \text{Base}\times \text{Height}) \\=2(xz+yz)$

Cost of building base = $0.75 per square foot

Total cost of building 4 walls =

$\text{Area of 4 walls}\times 0.75\\= 1.5(xz+yz)$

Total cost of building box =

$C(x,y,z) = 4.2xy + 1.5(xz+yz)\\C(x,y,z) = 4.2xy + 1.5xz + 1.5yz$
