Um well are u just adding and doing subtraction if so I think the answer is 12 idk I used calculator also I would need to know the answer choices I really don’t know if I’m right so don’t come at me
Answer:
D' = (5, 2)
Step-by-step explanation:
Try to join D and the origin using a line. Counterclockwise means in an opposite direction of rotation of the clock hands. So draw another line towards the right which is perpendicular to the previous line to fine the answer. Remember the length of the lines should be equal.

Answer:
A = 12
Step-by-step explanation:
Given A is inversely proportional to B then the equation relating them is
A = 
To find k use the condition when A = 4, B = 36 , then
4 =
( multiply both sides by 36 )
144 = k
A =
← equation of variation
When B = A , then
A =
( multiply both sides by A )
A² = 144 ( take square root of both sides )
A = ±
= ± 12
Since A is a positive number then A = 12
