Answer:

13

Step-by-step explanation:

N = 3^3 * 7^r

N has 16 integer factors

3^3 is 3 factors

That means 7^r must be 16-3 or 13 factor

7^r must be 13 terms

so 7^r must be 7*7*7..... *7  so that there are 13 term which means

r must be 13

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.
