Answer:
7
Step-by-step explanation:
To find the number, first multiply 8 by 3, since that is how you find the mean.
8 x 3 = 24 (total)
x + 6 + 11 = 24
x = 24 - 6 - 11
x = 7
Inverse:
7 + 6 + 11 = 24
Mean = 24/3 = 8
Hope this helps!
Answer:
Step-by-step explanation:
L1 -x + 2y = -1
L2 5x - 10y = 6
-x + 2y = - 1 multiply by -1
x - 2y = 1 multiply by 5
5x - 10y = 5 is similar that 5x - 10y = 6
The system has no solution
Answer:
<h2>
Letter C</h2>
Step-by-step explanation:
If we look on the number line we see that there is a point on -3, another point on -1, 2, and 7.
These points tell us our answer, but the question states it doesn't have to be in any order.
As we look at answer A we see -3, 1, 2, and -7. That's incorrect since there is no positive 1 nor an -7.
As we look at answer B we see -3, 7, 1, and -2. That's incorrect since there is no positive 1, and not a -2.
As we look at answer D we see -2, 3, 1, and 7. That's incorrect since there is no positive 2, no positive 3, and no negative 1.
C has to be the correct answer since it's the only answer left and has the 4 numbers that are on the number line.
Therefore, the correct answer is C.
Best of Luck to you.
