Diketahui f (x) = 3x + 10.jika f (p) = 1 dan f (r) = 13 maka hasil dari p x r adalah...
khominghoo
F (x) = 3x + 10. f (p) = 3p + 10 = 1 3p = 1-10 3p = -9 p = -9/3 = -3 f (r) = 3r + 10 = 13 3r = 13-10 3r = 3 r = 3/3 = 1 maka hasil dari p x r = -9 x 1 = -9
f (p) = 3p + 10 = 1
3p = 1-10
3p = -9
p = -9/3 = -3
f (r) = 3r + 10 = 13
3r = 13-10
3r = 3
r = 3/3 = 1
maka hasil dari p x r = -9 x 1 = -9
