Answer:
see below
Step-by-step explanation:
The slopes of parallel lines are the same. The slopes of perpendicular lines are negative reciprocals of each other, hence their product is -1.
___
For the most part, the concept of adding slopes of lines does not relate to parallel or perpendicular lines in any way.
Yes because no same x-valu resulted in different y-values.
The value of the expression 5x – 2y + (7x – y) when x = 7 and y = -2 is 90
<h3>How to evaluate the expression?</h3>
The expression is given as:
5x – 2y + (7x – y)
Substitute x = 7 and y = –2 in the above expression
5 * 7 - 2 * -2 + (7 * 7 + 2)
Evaluate the expression
90
Hence, the value of the expression 5x – 2y + (7x – y) when x = 7 and y = -2 is 90

The number of unique cookout trays are possible is 500
<h3>How many unique cookout trays are possible?</h3>
The given parameters are:
Main items = 10
Sides = 10
Drinks = 5
The number of unique cookout trays are possible is
Cookout trays = Main items * Sides * Drinks
So, we have:
Cookout trays = 10 * 10 * 5
Evaluate
Cookout trays = 500
Hence, the number of unique cookout trays are possible is 500
