Answer:
x = 9
Step-by-step explanation:
Well to find x we need to use the commutative property which is the moving of numbers and variables to either side of the equation,
|2x - 19| = 4x + 1
-2x to both sides
|-19| = 2x + 1
Absolute value of -19 is 19
19 = 2x + 1
-1 to both sides
18 = 2x
Divide 2 to both sides
x = 9
<em>Thus,</em>
<em>x is 9.</em>

Step-by-step explanation:
we can idnetify that it is arithmetic due to it being a linear sequnce. Therefore we find Tn and equate it to the last term to find the number of terms. We then use that to find the sum of the series using the following formula where n is the number of terms, a is the first term and L represents your last term.
Answer: y = x - 1
Step-by-step explanation:
The yellow points are located at the points (1, 0) and (8, 7)
For a linear equation that pases trough the points (x1, y1) and (x2, y2), the slope is:
s = (y2 - y1)/(x2 - x1)
Then, for our equation, the slope is
s = (7-0)/(8-1) = 1
Then our linear equation is
y = 1*x + b
where b is the y-axis intercept.
To find b, we can use that when x = 1, y = 0
0 = 1*1 + b
b = -1
Then our equation is y = x - 1
There are different data sets that have the same mean, median, and mode. Here's the data sets i got:
Set 1: 2,2,2,3,5,5
Set 2: 0,1,2,2,4,10
The mean for the 1st set is:
2+2+2+3+5+5= 19/6=3.1
The mean for the 2nd set is:
0+1+2+2+4+10= 19/6=3.1
The median for the 1st and 2nd set is:
2.5
And the mode (most common number) for the 2 sets is:
2
Hope this helps!! :-)
Sorry if I took to long, it took me awhile to come up with 2 sets that had different numbers, but had the same mean/median/ and mode.
