Answer:
taxable income = adjusted income - (deductions + Allowances/Exemptions)
Step-by-step explanation:
Taxable income is the type of income on which a person has to pay tax to the government. Taxable Income is calculated by subtracting the deductions and exemptions from the adjustable income.
With deductions you can either have itemized deductions or standard deductions.
Standard deduction consist of deductions like if a couple is married then they will have the deductions and if there are dependents of a person then he will have a standard deduction.
Itemized deductions consist of mortgages values, medical expenses, charity works etc.

Answer:
D
Step-by-step explanation:
a is false since x could be 0.
b is easy to check, just plug numbers in, and we can see that it's false(you would get 0+0=1 and -0-0=-1 once plugged in)
c is also easy to check, just plot the line or simplify the first equation. since (2x+2y)/2=4/2 is also x+y=2, the second equation is also x+y=2, so it must have infinitely many solutions.
d must be true due to process of elimination but let's check to make sure.
7y=14x, divide both sides by 7 to get y=2x and since they're the same equation it must mean that they have infinitly many solutions and we can see that it is correct
