Write the formula for calculating taxable income.
Harlamova29_29 [7]

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.

This will help us to find the value of our taxable income

For a given pair of points, find the equation of the line y=mx+b that goes through the points by solving a system of linear equa
rjkz [21]

Answer:

y = 2x - 3

Step-by-step explanation:

the formula for finding equation of a line is m = (y2 - y1 )/(x2 - x1). that is (7-3)/(5-3) which gives you 4/2 = 2.

you then chose one of the point and fill in the equation y - y1 = m (x -x1)

So let's chose (3,3) and fill in.

y - 3 = 2 (x - 3)

y - 3 = 2x - 6

y - 2x = -6 + 3

y - 2x = -3

Hence, the equation of the line is y = 2x - 3

the average age of 5 students is 9yrs out of them the ages of 4 students are 5,7,8,and 15yrs what is the age of remaining studen
valentinak56 [21]

Answer:

Step-by-step explanation:

Keep in mind that to find the average they would do:

Average = Sum of students' ages / number of students

So to solve this question we should firstly find the sum of all their ages.

To do this you multiply 5 by 9 = 45.

This means 45 is the sum of all 5 students' ages.

Next you are given four students have ages 5 , 7 , 8 and 15.

The sum of their ages are: 5 + 7 + 8 + 15 = 35

This means that the final student has age 45 - 35 = 10 years.
