Answer:
A. 4
Step-by-step explanation:
We can look at the number line and find B and A
we get
B=-7
A=3
now, we can find |B| and |A|


now, we can find
|B|-|A|
now, we can plug values


So,
option-A
Answer:
B. 88
Step-by-step explanation:
the total data = 1+2+4+5 = 12
the median is (a6+a7) /2
a6 = 87, a7 = 89
so, the median = (87+89)/2 = 88
Answer:
B (2,8)
Step-by-step explanation:
Answer:
Step-by-step explanation:
x/4-y/2=8, x-2y=32, x=32+2y
x/2+3y/4=-5, 2x+3y=-20, x=(-20-3y)/2
32+2y=(-20-3y)/2
64+4y=-20-3y
7y=-84
y=-12, since x=32+2y
x=32+2(-12), x=32-24=8
So the solution is the point (8, -12)
