Answer:
AB = b - a
Step-by-step explanation:
AB = -OA + OB
AB = -a + b we usually write the positive vector first
AB = b - a
We know that P divides AB in the ratio 3:1 so PB = 1/4 AB
AB is negative as we are going in the opposite direction
OP = OB - 1/4 AB
OP = b - 1/4 (b - a)
multiplying inside the brackets:
OP = b - 1/4b + 1/4a
OP = 3/4b + 1/4a
Answer:
Step 2 is incorrect.
Step-by-step explanation:
It's incorrect because I'm pretty you need to do inverse operation. To get 24 you must subtract, not add.
Answer:
Step-by-step explanation:
All the absolute value functions given in the option are of the form:
, where (h,k) is the vertex
From your description the absolute value graph has vertex at (-4,-2)
Hence h=-4 and k=-2.
We substitute to get:
We simplify to get:
