Please help me with this
Allisa [31]

Answer:

neither

Step-by-step explanation:

find the slopes of FG and HJ using the slope formula (y_2-y_1)/(x_2-x_1)

FG: (-1+3)/(-2-1)=2/-3=-2/3

HJ: (3-0)/(6-5)=3/1=3

perpendicular lines have slopes that are the negative reciprocal of each other. -2/3's negative reciprocal is 3/2 which isn't 3. the lines aren't parallel or perpendicular

Need help with this<br><br>what do median range mode and mean mean
Marysya12 [62]
Lets use this set of data as an example:
2,2,3,3,3,3,4,4,5

Median is the data number that is in the middle of all of the numbers when arranged from least to greatest.
The median would be 3 since its in the middle. THINK: Median=Medium

Range is the highest number minus the lowest number. This is easy.
5-2=3
So the range is 3.

The mode is the number that you see the most often. 3 is the most since there are four 3s. There can be more than one mode or even no mode. THINK: Mode=Most

The mean is all of the numbers added together and then divided by the number of numbers.
2+2+3+3+3+3+4+4+5= 29
29 divided by 9 = 3.2222222222(repeated)
The mean can also be called the average.

I hope this helps!!!

The asymptote of the function f(x) = 3^x+1 - 2 is ____. Its y-intercept is ____.
xxMikexx [17]
We are given the function <span>f(x) = 3^x+1 - 2 and is asked for the asymptote and y-intercept. In this case, we transform the function to

y +2 = 1/3^(x+1)-1
y = 1-2</span>/3^(x+1)-1/(3^(x+1)-1)
let 3^(x+1)-1 = 0
<span>1/3^(x+1) = 0
x = infinity
when x = infinity
y = 0 - 2
y = -2

The y-intercept is the value where x = 0. substituting, 

y = 3^(0+1) - 2 = 1 </span>
