Answer:
a.<55, -27>
Step-by-step explanation:
The given vectors are u = <7, -3>, v = <-9, 5>.
We want to find 4u - 3v.
We substitute the vectors and multiply by the scalars.
4u - 3v=4<7, -3>-3 <-9, 5>.
4u - 3v=<28, -12>- <-27, 15>.
4u - 3v=<28--27, -12-15>
4u - 3v=<55, -27>

Answer:
101/140
Step-by-step explanation:
<u>Solving in steps:</u>
- -6/15 * 4/7 - (-7)/20 * 4/7 + 3/4 =
- - 2/5 * 4/7 + 7/20 * 4/7 + 3/4 =
- - 8/35 + 7/35 + 3/4 =
- -1/35 + 3*35/4*35 =
- -4/140 + 105/140 =
- 101/140
