So, the absolute value of a negative number and the same number in positive terms is the same.
<span>Imagine a number line with zero in the middle, and numbers stretching out negative on one side and positive on the other. Measure out "3" on your number line in each direction. So, -3 and 3.
</span>
The absolute value of each of those — its distance from zero — is the same.
Does that make sense?
Answer:
last two numbers are 10,so their mean is 10
adding all means give us the mean of total data
Step-by-step explanation:
9514 1404 393
Answer:
D. (-3, -2)
Step-by-step explanation:
The equations have different coefficients for x and y, so will have one solution. The solutions offered are easily tested in either equation.
Using (x, y) = (-2, -3):
x = y -1 ⇒ -2 = -3 -1 . . . . False
Using (x, y) = (-3, -2):
x = y -1 ⇒ -3 = -2 -1 . . . .True
2x = 3y ⇒ 2(-3) = 3(-2) . . . . True
The solution is (-3, -2).

If you'd like to solve the set of equations, substitution for x works nicely.
2(y -1) = 3y
2y -2 = 3y . . eliminate parentheses
-2 = y . . . . . . subtract 2y
x = -2 -1 = -3
The solution is (x, y) = (-3, -2).
I'm going to label them from top to bottom 1,2,3,4,5
your answer is 3,4,5,2,1
