Tcecarenko [31]

Answer:

Step-by-step explanation:

If the original price is x and you deduct 3, you'l have x - 3.

If you buy 4 of them, you multiply that price by 4, giving you 4(x - 3).

Then, if that value is equal to 27, you get 4(x - 3) = 27

Answer:

(2000 - 100x)(5 + x)》12000

10000 - 500x + 2000x - 100x²》12000

-100x² + 1500x + 10000》12000

x for max profit:

-200x + 1500 = 0

x = 7.5

Price = 5 + 7.5 = 12.5

Max profit:

(2000 - 100(7.5))(5 + 7.5)

= 1250 × 12.5

Using math, determine the exact rate of change for.the increase (warm up). Explain how you got your answer.

andriy [413]

Answer:

Step-by-step explanation:

To find the rate of change for the increase (warm up), use the coordinate pair of any two points on the line that slopes upwards in the graph.

Let's use the following:

At 5 mins (x), heart beats (y) is 80 => (5, 80)

At 10 mins (x), heart beats (y) is 100 => (10, 100)

Rate of change = $\frac{y_2 - y_1}{x_2 - x_1}$

$= \frac{100 - 80}{10 - 5}$

$= \frac{20}{5} = 4$

Rate of change is 4.
