Answer:

When graphing a linear inequality on a number line, use an open circle for "less than" or "greater than", and a closed circle for "less than or equal to" or "greater than or equal to".

Answer:

See explanation for answer.

Step-by-step explanation:

When the point on the number line is an open circle, that means that the inequality does not include that exact value. For instance, in this case the inequality only takes number higher than, but not equal to, -1. Hope this helps!

No, 6,500 is one hundred times as much as 65, because of the two zeros on the end. 100 and 6,500.

<em><u>The polynomial that represents the difference between the cost of distributing by train and the cost of distributing by truck is:</u></em>

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

<em><u>Solution:</u></em>

<em><u>The cost of distributing by train can be modeled as:</u></em>

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

<em><u>The cost of distributing by truck can be modeled as:</u></em>

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

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
