given the graph function below which of the following ordered pairs are found on the inverse function
xenn [34]

Answer:

Option A.

Step-by-step explanation:

Graph of function has been given in the figure.

Coordinates of the points lying on this graph will be

x     -2        -1         0          1        2

y    -10       -3        -2         -1        6

Therefore, coordinates of the points which will lie on the inverse of this function will be

x     -10      -3        -2       -1       6

y      -2       -1         0        1       2

Therefore, Option A. will be the answer.

The average of four numbers is 98. If three of those numbers are 86, 87, and 91, what is the fourth number?
BabaBlast [244]

Answer:

128

Step-by-step explanation:

86 plus 87 plus 91 =264  

You have to get 98 times 4 which is 392  

Then;

392-264, which is 128, which is the answer (the fourth number)  

So;

86+87+91+128 = 392 divided by 4 (the number of numbers there is) which equals 98!  

Hope it helped

2x + 4y = 12 y = x – 3 What is the solution to the system of equations?
sergeinik [125]
2x+4y=12
y=x-3

Since we know what y equals, we can plug this into the first equation:
2x+4(x-3)=12
We can then distribute:
2x+4x-12=12
And solve for x:
6x-12=12
6x=24
x=4
We can then plug x into the second equation and find y:
y=x-3
y=4-3
y=1

Therefore x=4 and y=1

Fourth-grade classrooms in several elementary schools are randomly assigned to different antibullying training programs at the b
Anastasy [175]

Answer:

experimental study.

Step-by-step explanation:

This study is an example of an experimental study.

The type of training program is the independent variable. The number of incidents of bullying is the dependent variable.

Since the participants of our study are affected directly in the research (the fourth-grade children) by not training against anti-bullying, the study is experimental research.

An independent variable is one that is somehow controlled or adjusted to evaluate the effects of a different variable, the dependent. Since we control whether we do bullying training here or not, our kind of training program is our independent variable, which is our dependent variable since we measure its impact on instances of bullying no.
