pliss bantu jawab gais :)

a.
bayangan -5 → [tex] \frac{1}{2} [/tex] . -5 = -2,5 / -2[tex] \frac{1}{2} [/tex]
bayangan 0 → [tex] \frac{1}{2} [/tex] . 0 = 0
bayangan 10  → [tex] \frac{1}{2} [/tex] . 10 = 5 

b.
[tex] \frac{1}{2} [/tex]x = 3
x = 2. 3
x = 6

c. 
0, karena semua yang dikali 0 = 0

(dari kiri ke kanan, saya tulis dari atas ke bawah)
[tex] \frac{60}{x} [/tex]
[tex] \frac{60}{-5} [/tex] = -12
[tex] \frac{60}{-4} [/tex] = -15
[tex] \frac{60}{-3} [/tex] = -20
[tex] \frac{60}{-2} [/tex] = -30
[tex] \frac{60}{-1} [/tex] = -60
[tex] \frac{60}{1} [/tex] = 60
[tex] \frac{60}{2} [/tex] = 30
[tex] \frac{60}{3} [/tex] = 20
[tex] \frac{60}{4} [/tex] = 15
[tex] \frac{60}{5} [/tex] = 12

b.
(-5,-12), (-4,-15), (-3,-20), (-2,-30), (-1,-60), (1, 60), (2, 30), (3,20), (4, 15), (5,12)
