Question

Kak bantuin ini juga ya plisss tapi jangan ngasal

Answer 1

7. B⁻¹=
 = 1/(3+2) [1....-2]
                 [1....3]

= 1/5[1...-2]
........[1....3]

= [1/5 ...-2/5]
...[1/5.....3/5]

8. a = 3, r = 3
s6 = a(r⁶ -1)/(r-1) = 3(3⁶-1)/(3-1)
s6 = (3/2)(728) = 1.092

9. (3,2 ) + (2, -1) = { (3+2), (2-1)} = (5, 1)

10. A(x,y)---sb x---> A'(x, -y)
A(-1,3) ----> A" (-1, -3)
