The graph of the equation is attached in the figure below
Step-by-step explanation:
We need to make the graph of the equation: 
Solving the equation:
Applying absolute rule: |u|<a, a>0 then -a<u<a
So,

Answer:
x = 2 | y = 3. ( 2,3 )
Step-by-step explanation:
2(3x + 3y = 15)
6x + 6y = 30
3(4x + 2y = 14)
12x + 6y = 42
- 6x. -6y. -30
6x = 12
÷ 6. ÷6
x = 2
3x + 3y = 15
3(2) + 3y = 15
6 + 3y = 15
-6. -6
3y = 9
÷3. ÷3
y = 3
Answer:
Relative frequency:
The most serious threat to aviation safety is, according to this data, "mechanical failures". It can be improved by more rigorous inspection and better maintenance policies and execution.
Step-by-step explanation:
We have the data for fatal plane crashes. The sum of plane crashes is
We can calculate the relative frequency as:
We can see that the most frequent cause is "mechanical problems", with a relative frequency of 0.45.
D. divide them by 25 and there it is
To solve:
1) Divide both sides by 100
100x/100 = 265/100
x = 2.65
