Well they each have 3 solutions
The solutions to 7x-7y=-6 are:
- Slope=1
- X-intercept= - 6/7=-0.85714
- Y-intercept= 6/7= 0.85714
The answers to 13x-9y=16 are:
- Slope=2.889/2.000=1.444
- X-intercept=16/13=1.23077
- Y-intercept=16/-9=1.77778
- Hope i could help you
Answer:
36+63i
explanation:
You would need to write a solvable equation, and you can do this because you know that angles in a triangle add up 180° so the missing angle must be (180 - 9x). This makes the equation:
5x + 9 + x + (180 - 9x) = 180
6x + 9 + 180 - 9x = 180
-3x + 189 = 180
- 189
-3x = -9
÷ -3
x = 3
So your answer is x = 3, I hope this helps!
There are seven (7) friends.
The first friend to board can be any one of the 7. For each of them ...
The 2nd one to board can be any one of the remaining 6. For each of them ...
The 3rd one to board can be any one of the remaining 5. For each of them ...
The 4th one to board can be any one of the remaining 4. For each of them ...
The 5th one to board can be any one of the remaining 3. For each of them ...
The 6th one to board can be either of the remaining 2. For each of them ...
The 7th one to board is the last 1 standing.
The number of different ways that this could play out is
(7 x 6 x 5 x 4 x 3 x 2 x 1) = <em>5,040</em>
