Answer:

x≤-3 2 ≤x<7

Step-by-step explanation:

(x^2+x-6) /(x-7) ≤0

Factor the numerator

(x+3)(x-2) / (x-7)≤0

Critical points are

X =-3 X =2 X=7

We need to check the values when

x≤3 -3 ≤ x≤2 2 ≤x<7 x>7

(x cannot be 7 because then the denominator is zero)

and see when it is less than 0

Substitute a value in and see if factor is positive or negative

x≤-3

(negative)(negative) / (negative) = negative

-3 ≤x≤2

(positive)(negative) / (negative) = positive this range does not work

2 ≤x<7

(positive)(positive) / (negative) = negative

x>7

(positive)(positive) / (positive)

The cost in dollars of producing x vehicles for a company is given by C(x)=1200x+5500

GarryVolchara [31]

The rate of change represents the variable production cost rate. The production cost is increased in 1200 units per each additional manufactured car.

<h3>Interpretation of a linear function</h3>

Let be $C$ and $x$ the production cost and the number of vehicles produced, it there is a linear relationship between the two variables, then we have the following formula:

$C(x) = \dot r \cdot x + C_{o}$ (1)

Where:

$C_{o}$ - Fixed production costs.
$\dot r$ - Variable production cost rate.

In a nutshell, the rate of change represents the variable production cost rate. The production cost is increased in 1200 units per each additional manufactured car. $\blacksquare$
