Diketahui rumus g(x) = 5x + 4. jika g(a) = 44, nilai a – 3 adalah.. tolong caranya
Jawaban Terkonfirmasi
5x + 4 = 44
x = (44-4)/5, x = 8
Jadi, nilai a-3 = 8 – 3 = 5
Jawaban Terkonfirmasi
G(x) = 5x+4
Karena g(a) = 44
5x+4 = 44
pindah 4 ke ruas kanan
5x = 44-4
5x = 40
x = 40/5
x =8
berarti a = 8
a-3 = 8-3 = 5
