Pre-Calculus - Identify where a function is increasing decreasing or constant from the graph

Example: The graph shown above is decreasing from the point (3,4) to the point (5,-5), described as decreasing when 3 < x < 5. Using interval notation, it is described as decreasing on the interval (3,5). Constant: A function is constant, if as x increases (reading from left to right), y stays the same.

Answer:

use the slope formula

Step-by-step explanation:

Usually, you are asked for an average slope over some interval. The slope is calculated on that interval the same as it would be if you were given two points, one at each end of the interval.

m = (y2 -y1)/(x2 -x1)

For example, if you wanted to know the slope on the interval [1, 2] hours, the points you would use would be ...

(hours, miles) = (1, 25) and (2, 75)

The corresponding slope on that interval is ...

m = (75 -25)/(2 -1) = 50 . . . . miles per hour

You can identify four (4) regions on this graph in which the slope is constant:

(0, 1) . . . slope is 25 mph

(1, 2) . . . slope is 50 mph, as computed above

(2, 3) . . . slope is 0 (the rider has stopped)

(3, 5) . . . slope is 25 mph

Over different intervals, you need to identify the points involved and use the formula to compute the average slope.

Two parallelogram-shaped pieces of tile have the same area. One has a base of 20 centimeters and a height of 15 centimeters. The

gtnhenbr [62]

Answer:

height = 12 cm

Step-by-step explanation:

Parallelogram 1:

Area = base *height = 20 * 15 = 300 sq. cm

Area of parallelogram 2 = area of parallelogram 1

25 * height = 300

height = 300/25

height = 12 cm

What is the value of |−8.6| a −8.6 b −1.4 c 1.4 d 8.6 thanks

nikklg [1K]

Hi!

When a number has lines on the outside of it like that, it means that it's the distance from 0. It's known as the absolute value.

|−8.6|'s distance from 0 is 8.6.

The answer is d 8.6

Hope this helps! :)

Which of the following indicates the subtraction property of equality when solving the equation 4(x + 9) + 5 = 3x − 8? Question

jeka94

Answer: 4(x + 9) = 3x − 8 − 5

Step-by-step explanation:

Hi, to answer this question we have to analyze the equation given:

4(x + 9) + 5 = 3x − 8

The subtraction property of equality states that if we subtract the same number from both sides of the equation, the equality remains.

So, if we subtract 5 from both sides:

4(x + 9) + 5-5 = 3x − 8 -5

4(x + 9) = 3x − 8 − 5

Feel free to ask for more if needed or if you did not understand something.
