Y = 2/3x + 5....slope here is 2/3...so the line is increasing...going up....the 5 in the equation is ur y int, where the line crosses the y axis....so this equation will be line 4

y = x - 3....slope is 1....increasing....y int is -3....this is line 1

y = -3/4x + 3....slope is -3/4.....this one is decreasing...going down...the y int is 3....so this is line 2

y = -1/2x - 4....slope is -1/2...so this is decreasing...y int is -4...so this one is going to be line 3

x² - x - 12 = 0

$x = \dfrac{-b \pm \sqrt{b^{2} - 4ac}}{2a}$

a = 1, b = -1, c = -12

$x = \dfrac{1 \pm \sqrt{(-1)^{2} - 4(1)(-12)}}{2(1)}$

x = 4 or -3

Six customers enter a gift shop during a 3-hour period. On average there are 0.25 customers in the gift shop and each spends 7.5

Stolb23 [73]

Answer:

6 is most directly associated with the flow rate of customers

Step-by-step explanation:

Reason:

0.25 is the number of customers in the gift shop at a given point of time is WIP inventory

7.5 is the average time spent by customer in the shop and it is the throughput time.

Flow rate = WIP inventory/Throughput time

=0.25/7.5

= 0.0333 per minute = 2 per hour or 6 per 3 hour as given in question.

If c (x) = StartFraction 5 Over x minus 2 EndFraction and d(x) = x + 3, what is the domain of (cd)(x)?

Volgvan

Answer:

The domain of the function (cd)(x) will be all real values of x except x = 2.

Step-by-step explanation:

The two functions are $c(x) = \frac{5}{x - 2}$ and d(x) = x + 3

So, (cd)(x) = $(\frac{5}{x - 2})(x + 3) = \frac{5(x + 3)}{x - 2}$

Then, for x = 2 the function (cd)(x) will be undefined as zero in the denominator will make the function (cd)(x) undefined.

Therefore, the domain of the function (cd)(x) will be all real values of x except x = 2. (Answer)
