NeX [460]

Answer: $53,330

Step-by-step explanation:

This is an exponential function so to find the salary in 3 years, you need to use a future value formula such as :

= Amount * ( 1 + rate) ^ number of years

Amount = $51,000

Rate = 1.5%

Number of years = 3 years

Salary = 51,000 * ( 1 + 1.5%)³

= 53,329.59

= $53,330

Express y=3x+2 in general form
katrin [286]

General form of a linear equation is ax+by+c=0 where a,b, and c are three real numbers.

So, we can shift all the terms in one side of the equation. Hence, first step is to remove y from the left side. So, subtract y from each sides.

y-y=3x+2-y

0= 3x - y +2 (By simplifying)

So, the general form of the given equation is 3x-y+2=0.
