Ответ:
only (-1, -5)
Step-by-step explanation:
If x= -1 and y= -5
(-5)+5= 2((-1)+1)= 0
Ответ:
y+5 = 2x+2
y-2x = 2-5
y-2x = -3
2x-y = 3
2(5)-(10) = 3
10-10 = 3
0 = 3
option A is incorrect
2(-1) - (-5) = 3
-2 + 5 = 3
3 = 3
Option B is correct
Ответ:
B. 12

Based on the centroid theorem,
BP = 8
Plug in the value of BP into the equation and find the value of BF.
Cross multiply
Divide both sides by 2
