ANSWER
See below
EXPLANATION
Given the system of linear equation:
If
then the two equations, will intersect at one. The system has unique solution.
If
then, the two equations are parallel and the system will not have a solution.
If
Then, the two equations will coincide.
There is infinitely many solutions.
Variable: not consistent or having a fixed pattern liable to change. Or able to be changed or adapted.
Sorry that is all I know and I need a picture
Answer:
Step-by-step explanation:
Consider the triangle XYW.
<u>Since ∠X is right angle, the other two angles are complementary:</u>
Also, VWX and ZYX are straight angles, which are equal to 180°.
<u>According to angle addition postulate we have:</u>
- m∠Y = 180° - 4x and
- m∠W = 180° - 6x
<u>Add up the above two and compare with first sum, then solve for x:</u>
- m∠Y + m∠W = 90°
- 180° - 4x + 180° - 6x = 90°
- 360° - 10x = 90°
- 10x = 270°
- x = 27°
I would say all of them can be model as functions.
<span>model number:
This would be a onto function, meaning that the outputs are not unique.
f(model_1) = f(model_2) = computer_type.
</span><span>part number:
</span>This would mean the function takes in multiple parameters.
f(part_1, part_2, part_3, ...) = computer
<span>serial number:
This is the most obvious one; an one-to-one function:
f(s_num_1) = computer_1;
f(s_num_2) = computer_2;</span>
