2. Explanation X and Y are whole numbers.
X% Y finds the remainder after you divide X by Y.
For example, 7 % 3, means divide 7 by 3 and determine what is left over (7 divided by 3
equals 2 and the remainder is 1). So, 7% 3 equals 1.
Question
If X is a number. Which of the following will find the last digit of X?
For example, the last digit of 1327 is 7.
O A:X% 2
O
B:X%3
O C:X% 5
O D:X% 10
O EX% 100

The remainder of a division is the whole number, after the complete division. The expression that finds the last digit of 1327 is:

Given that:

To do this, we simply test the given options.

When 1327 is divided by 2,

The result is 663, remainder 1

So, we have:

When 1327 is divided by 3

The result is 442, remainder 1

So, we have:

When 1327 is divided by 5

The result is 265, remainder 2

So, we have:

When 1327 is divided by 10

The result is 132, remainder 10

So, we have:

When 1327 is divided by 100,

The result is 13, remainder 27

So, we have:

Hence, the expression that finds the last digit is:

Because the result is 7

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0
