The slope is -3 because the coefficient of x is the slope of a line, and -3 × x=-3x. The other numbers do not affect the slope, just the positioning of the graph as they are not related to x
The answer is B. This is because we know this is 6 more than 3 times the number of students that played last year. A and C makes no sense. D does not make any sense because it is 6 more not 6 less.
(2k + 3k) + (9k - 7k + 8)
(5k) + (2k + 8)
7k+8
7k + 8 is the answer
2 times . 18*2=36 The answer is 2
Option C
When
is subtracted from
then the result is 
<h3><u>Solution:</u></h3>
Given that
is subtracted from 
We have to find the result
Subtraction is a mathematical operation that tells us the difference between two numbers.
When "a" is subtracted from "b", we write in mathematical expression as "b - a"
So
is subtracted from
is written mathematically as:

<em><u>Expanding the above expression using algebraic identity:</u></em>


Multiplying the nnegative sign with terms inside bracket
<em><u>There are two simple rules to remember: </u></em>
- When you multiply a negative number by a positive number then the product is always negative.
- When you multiply two negative numbers or two positive numbers then the product is always positive.

Hence the result is:
