Rashawn read 25 pages of his book each day until he finished the book. His book was 400 pages long.
Katyanochek1 [597]

The first thing we are going to do for this case is define variables.

We have then:

x: number of days

y: number of pages remaining.

We write the linear equation that models the problem:

y = -25x + 400

The intersection with the vertical axis is:

We evaluate x = 0:

y = -25 (0) + 400\\y = 0 + 400\\y = 400

We get the point:

(x, y) = (0, 400)

The intersection with the horizontal axis is:

We evaluate y = 0:

0 = -25x + 400\\25x = 400

x = \frac{400}{25}\\x = 16

We get the point:

(x, y) = (16, 0)

Answer:

The graph is:

y = -25x + 400

Graph located in the bottom left.

G = {(5, 3), (2, 3), (6, 4)} Is G-1 a function and why?
galben [10]
To get G^-1 all we need to do is flip the points around Example for (5,3) make it (3,5)
Here are the points in inverse (3,5); (3,2); (4,6)
To tell if a group of point can be a function we need to 1st look at the x values.  If all the x values are different, then it is a function (the x's are not all different)
If there are x values that are the same, they MUST have the same y value.
look at the points (3,5) and (3,2) those have the same x but they go to different y values so it is not a function.

You can think about it like this.  Can you go to more than 1 place at the EXACT same time?  Obvious answer is no. Can you have multiple people go to the same room?  Sure that is possible.  Same with functions.  An x value can ONLY go to 1 y value, and many different x values can go to the same y value.

blsea [12.9K]

To solve the inequality:

-6

Add 1 to the sides of the inequality:

-6+1

Then

-5

Dividing all the inequality by 5, we have:

\frac{-5}{5}

Graphically:

Or, in the interval notation(-1, 1/5).
