Answer:
The value of the expression increases as j decreases
Step-by-step explanation:
Let 

As j decreases, the value of j300 decreases (i.e the farther j300 is from 150). Due to the wider gap between 150 and j300, the value of f(j) increases.
For example:
When j = 1, f(j) = 150 - (300*1) = -150
When j = 0.5, f(j) = 150 - (300*0.5) = 0
When j = 0. f(j) = 150 - (300*0) = 150
It is obvious from the analogy above that the expression 150-j150−j150 increases as j decreases
2r-6+5r=3-r+7
7r-6=10-r
7r+r=10+6
8r=16
r=16/8
r=2
Answer: c. box and whisker plot
Step-by-step explanation:
the box and whisker plot shows you the median and lays out the data so you would know how spread how your numbers are
Y=6x+1
y=6(5)+1
y=30+1
y=31
D. (5, 31)
hope this helps!
