Answer:
Page 1: 2u - 3v = < -7, 1 >
Page 2: < -7, 9 >
Step-by-step explanation:
Page 1: Given u and v, we need 2u - 3v. With vectors, you can multiply both terms by any scalar (the coefficient, i.e. 2u, the 2 is the scalar)
2u = 2<1, 2> = <2, 4>
3v = 3<3, 1> = <9, 3>
So 2u - 3v = <2, 4> - <9, 3> = <2 - 9, 4 - 3> = <-7, 1>
Page 2: The same steps apply, but when you see i and j, the coefficient of the i term is the x value, and the coefficient of the j term is the y value, so
3u - 2v = 3< 1, 1> - 2<5, -3> = <3, 3> - <10, -6> = <3 - 10, 3 - (-6)> = <-7, 9>
There were 4 musicians in the bad last month
The time taken by the bug will be 5 seconds and the formula used to calculate time is T = D/S.
<h3>What is speed?</h3>
The distance covered by the particle or the body in an hour is called speed. It is a scalar quantity. It is the ratio of distance to time.
We know that the speed formula
S = D/T or T = D/S
where T is time, D is distance, and S is speed.
If a bug travels 5 meters across the floor if it is traveling 1 meter/second. Then the time taken by the bug will be
T = 5/1
T = 5 seconds
More about the speed link is given below.

Now I don’t know if this is right but I’m pretty sure it’s just 24 with simple subtraction
