Answer:
Concept: Physics Qualitative Analysis.
- Scalar values are constant and compared to vector values they do not have a direction or magnitude or a gradient representation.
- Lets get started by setting up the equation
- They want us to find 3U-2V
- Given U= <6,6> V=<6,-6>
- Now we plug in and solve!
- 3<6,6>- 2<6,-6>
- <18,18>-<12,-12>
- Subtract
- <18-12,18-(-12)>
- Hence that gives us a result of <6,30>
- Now with the skills you gained solve the rest!!!

5. A slope is a line nevertheless and it keeps changing, while the rise over run is also a slope. This means that the only correct answer can be a 2 dimensional figure.
I believe the answer would be 6:5 because you divide both 18 and 15 by 3.
Answer:
The larger of the two angles is x, which is 75. y is the smaller angle at 15.
Step-by-step explanation:
In order to find these, we can use our solved value for y in the second equation to plug into the first equation. This method is called substitution.
x + y = 90
x + (1/5x) = 90
1.2x = 90
x = 75
Now we can plug that value into either equation to find y
y = 1/5x
y = 1/5(75)
y = 15
