Answer:
$45000
Step-by-step explanation:
Given data
Net income =$50,400
Let the prior year income be x
12/100*x +x= 50400
0.12x+x= 50400
1.12x= 50400
x= 50400/1.12
x= $45000
Hence the prior year income is $45000
(12.2,-6.4)
The results from Desmos are as shown.
The displayed values are (12.294, -6.353)
80
89^2-39^2=6400, 6400=80^2
the answer is x=-1/3
