The domain of the graph is {-3, -1, 1, 4}. The range of the graph is {-4, -1, 1, 4}

The domain of the set of ordered pairs is {-4, -3, 1}. The range of the set of ordered pairs is {1, 3, 4}

====================================================

Recall that the domain is the set of allowed x values. All we do is list the unique x coordinates of each point which are -3, -1, 1 and 4. The range is the set of y values so we just list the unique y coordinates of each point which are -4, -1, 1 and 4.

The same will happen with the other problem as well. The set of points listed is pretty much identical to the first problem, but the points haven't been graphed, but instead their coordinates have been listed out. The first coordinate is the x coordinate. The second coordinate is the y coordinate. Each point is in the form (x,y).

In the pup tent shown at the right, the two sides meet at the top to form a 72 angle. If the tent pole bisects the angle, what a

Sphinxa [80]

Answer:

36°

Step-by-step explanation:

The image of the question is obtained online and attached to the solution of this question.

The tent pole is the line in the middle of the triangle and it is stated explicitly in the question that this tent pole bisects the angle that the two sides make with each other at the top.

So, the angle that the tent pole makes with each side = (72°/2) = 36°

Hope this Helps!!!

What is the product of − 3/11 and − 2/15? please explain.

emmainna [20.7K]

ANSWER

The product is

$\frac{2}{55}$

EXPLANATION

To find the product of

$- \frac{3}{11}$

and

$\frac{ - 2}{15}$

means we should multiply the two fractions.

We multiply to obtain,

$- \frac{3}{11} \times - \frac{2}{15}$

$= - \frac{3}{11} \times - \frac{2}{3 \times 5}$

Cancel the common factors:

$= - \frac{1}{11} \times - \frac{2}{5}$

Now, multiply the numerators separately and the denominators too separately.

$= \frac{ - 1 \times - 2}{11 \times 5}$

This simplifies to,

$= \frac{2}{55}$

Ms.Carger has has to send some emails in the afternoon.It takes her 3 minutes to start up her computer and log-in to her email,

butalik [34]

Answer:

Ms. Carger would have sent $\frac{x-3\\}{7} \\$ emails in x minutes

Step-by-step explanation:

Firstly, Ms. Carger takes her 3 minutes to start up her computer and log-in to her email.

Therefore in x minutes, after starting up her computer and logging-in to her email, she would have x minutes minus the time used to start up her computer and log-in to her email. this implies she would have (x-3) minutes left for sending emails.

Since it takes 7 minutes to write and send each email, in (x-3) minutes she would be able to send only $\frac{x-3}{7}$ emails.

Therefore equation to represent the number of emails she can send in x minutes is $\frac{x-3}{7}$ emails
