The polynomial that represents the difference between the cost of distributing by train and the cost of distributing by truck is:

$f(x) = -0.04x^2 + 18x + 75$

Solution:

The cost of distributing by train can be modeled as:

$-0.07x^2 + 40x - 105$

The cost of distributing by truck can be modeled as:

$-0.03x^2 + 22x - 180$

where x is the number of tons of product distributed

To find: Difference between the cost of distributing by train and the cost of distributing by truck

Difference = cost of distributing by train - cost of distributing by truck

Let f(x) = difference in cost between trains & trucks

$f(x) = (-0.07x^2+40x-105) - (-0.03x^2 +22x - 180)$

$f(x) = -0.07x^2 + 40x -105 + 0.03x^2 -22x + 180$

$Combine\ the\ like\ terms\\\\f(x) = -0.07x^2 +0.03x^2 + 40x - 22x +180-105\\\\Add\ the\ like\ terms\\\\f(x) = -0.04x^2 + 18x + 75$

Thus polynomial that represents the difference between the cost of distributing by train and the cost of distributing by truck is found

Answer:

y= $\frac{3}{4}$ = 0.75

Step-by-step explanation:

To subtract the second equation from the first equation, you have to divide the equation as left of the equal sign and right of equal sign then do the calculation separately. The calculation will look like this

-3x +2y = 7

-3x - 2y = 4

_____________ -

(-3x +2y) - (3x -2y) = 7 - 4

-3x + 2y + 3x + 2y = 3

4y= 3

y= $\frac{3}{4}$ = 0.75

8. A blueprint of a house has a scale of 1 in: 6 ft. If a bedroom has a width

natulia [17]

A blueprint of a house has a scale of 1 in: 6 ft. If a bedroom has a width

of 2 in on the blueprint, what is the actual width of the bedroom?

So 1 inch on the blue print = 6 feet irl (in real life)

So 2 inch on the blue print = 6*2 = 12 feet irl

So the actual width of the bedroom is 12 feet.
