1) Subtract 1,000 from 16,000.
Now you have 15,000.
2) Divide 15,000 by 3.
The original price of the car was $5,000.
Since there's a common denominator, you can go straight into subtracting,
so for the top, x^2 + 8x - x^2 -2x + 6 will simplify to -6x -6 which with the bottom can be reduced (dividing everything by 3) to 2x - 2/x^2 + x
The rules are necessary, so that there is agreement as to how to evaluate an expression. By having rules, and having everyone follow the rules, an expression can have only one single correct value. If there are no rules, then different people will interpret the expression differently, and will get different values for its evaluation.
Answer:
Forces that are equal in size but opposite in direction are called balanced forces. Balanced forces do not cause a change in the motion of objects. Forces that cause a change in motion of objects are called unbalanced forces. Unbalanced forces can change the motion of an object in two ways.
I am assuming having no slope would be when a line is undefined, that would mean it is a vertical line <span>a line with 0 slope would actually be a straight horizontal line.</span>
