Answer:
B
Step-by-step explanation:
15+15=30
30/9=3 r3 doesn't work
30+15=45
45/9=5
Answer:
-2x+1
Step-by-step explanation:
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>
Answer:
13/15
Step-by-step explanation:
2 1/6= 13/6
2 1/2= 5/2
13/6 divided by 5/2 = 13/6 times 2/5= 26/30
simplify 26/30 = 13/15
