Expression: x - 7437 = 1400
answer: 1400 + 7437 = 8837 (x)
hope this helps! comment if further explanation is needed :)

Step-by-step explanation:
From the question we are told that:
Sample size 
Mean 
Standard deviation
Significance Level 
From table
Critical Value of 
Generally the equation for momentum is mathematically given by




In simplest form it is 3 over 4
There is a graphing calculator called desmos hope it helps
Find slope first
Two points: (-5,-2) and (5,4)
(4+2)/(5+5) = 6/10 = 3/5 slope
So far: y = 3/5x + b
Plug in any of the point
-2 = 3/5(-5) + b, b = 1
Final equation: y = 3/5x + 1
