Answer:
604800 possibilities
Step-by-step explanation:
There are two sets.
The first set is for the first five machining operations. This set has the following operations: A,B,C,D,E
The first operation to be made can be any of them(A,B,C,D,E). The second will be any of the four remaining ones, the third will be any of the three remaining and so on...
So for the first set there are 5*4*3*2*1 = 5! = 120 possibilities.
Now for the second set, the same logic is applied.
There will be 7*6*5*4*3*2*1 = 7! = 5040 possibilities.
Now taking into account all the 12 operations, separated by set, there will be 120*5040 = 604800 possibilities.
You can understand this calculus as that for a simple possibility of the first set, there are 5040 possibilities of the second set. The are 120 possiblities in the first set, so we have the multiplication in the paragraph above.
x = -2.5 is a vertical line. The vertical graph of the equation is shown in the image attached below.
<h3>What is the Equation of a Vertical Line?</h3>
The slope of a vertical line is undefined, therefore, the equation of a vertical line is expressed as x = a, where a is the x-intercept.
Given x = -2.5, the equation suggests it is a vertical line, where the line intercepts the x-axis at -2.5, which is the x-intercepts.
Thus, the graph for x = 2.5 is shown in the diagram below.

Answer:
The equations of the lines are y=3 and y=8.
Parallel lines have equal slopes, so if the slopes are opposites, the slopes must be 0.
A line with this slope and passing through (7, 3) has equation y=3.
Step-by-step explanation:
The above answer statements pretty much speak for themselves. The only opposite numbers that are equal are 0 and -0 = 0, so the slopes must be 0.
A line with a zero slope has a constant y-value, so is of the form ...
y = constant
If it goes through a point with a y-coordinate of 3, then the constant must be 3. The line is ...
y = 3
___
If the sum of two numbers is 11 and one of them is 3, the other is 8. So, the parallel line has equation y = 8.
