Answer:
True
Explanation:
First of all its necessary remember that a linear system is a compound of multiple equations that involve variables.
<h2>Existence:</h2>
Depending on the number of equations and the number of variables, you could determine if the linear system has a solution or not. There are 3 possibilities:
- If the linear system has more equations than variables could exist infinite answers.
- If the linear system has more variables than equations, it is considered an undetermined system and you neer more information to solve it.
- If the linear system has the same number of equations and variables, the system is consistent and has at least one solution.
<h2>
Uniqueness:</h2>
If possibility 3 is presented, it becomes necessary know if its the only one solution or exists more than one solution.

Assuming you want to find the length of the longest line segment, you would have to first determine where the longest line segment is.
If you can't do this straight away, then it'd be good to draw a diagram as I shown below, to visualise.
From there, you apply pythagora's theorem to the dimensions of the rectangular prism to find the length of the longest line segment.
I have attached the solution in a photo, including some explanation. Hope it helps :)
Answer:
Step-by-step explanation:
In this question we have to find the expression for the value of temperature in terms of degrees Celsius.
Since, the given expression is,
F = 1.8C + 32
F - 32 = 1.8C + 32 - 32
F - 32 = 1.8C


For F = C,

C - 32 = 1.8C
C - 1.8C = 32
-0.8C = 32
C = 
C = -40
Therefore, at (-40°C) degrees of temperature degrees Fahrenheit and degrees Celsius are equal.
Answer:
15
Step-by-step explanation:
Apply absolute rule: | a | = a, a ≥ 0
| 13 | = 13
= 13 + | -2 |
| -2 | = 2
= 13 + 2
= 15
