Question

Tolong bantuin ya pake caranya juga

Answer 1

A. (x dany=xy berarti 2+3 .......5xy

Answer 2

29)
persamaan garis g  adalah 2x +3y = 6
garis h tegak lurus  g melalui O(0,0) adlah 3x - 2y = 0

30)
g -> 4x - 4y + px +py + 8 = 0
(4+p)x + (-4+p) y + 8 = 0
m1 = -(4+p) / (-4+p) 

h-> 4x +2y - 3x +6y +5 = 0
(4-3)x +(2+6)y + 5= 0
x + 8y + 5 = 0
m2= -1/8
g tek lurus h maka m1.m2 = -1
m1 = -1/(m2) = 8
-(4+p)/(-4+p) = 8
-4 - p = -32 + 8p
-9p = 28
p = 28/-9
(4+p) x + (-4+p) y +8 = 0
(8/9) x  -64/9 y + 8 = 0
8x - 64 y + 72 = 0
x - 8y + 9 = 0
