Let K be a circle with centre P and radius r, and let L be a circle with centre O and radius 2r, which passes through P. Let A, B be points on K and C, D points on L, such that lines AC and BD are tangent to both circles. Show that points A, P, D are collinear

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.

236 cm 16 time 12 = 192

6 times 7 = 42

192+42

cause it equals more
