Answer:
Move downward by 7 units
Move leftward by 6 units
Step-by-step explanation:
Given

Required
The transformation from the current location to the new location
To do this, we pick two corresponding points on the current location and the new location.
We have:
-- Current location
-- New location
First, move A downwards by 7 units.
The rule to this is:
So, we have:
Next, move the above points leftward by 6 units.
The rule to this is:
So, we have:
Pythagoras' theorem:
b^2 = c^2 - a^2
Substitute in the values:
b^2 = 13^2 - 12^2
b^2 = 25
Square root it
b = 5km
The answer is option B. 5km
Answer: y = -3(x + 
)² + 
, 
, 
<u>Step-by-step explanation:</u>
First, you need to complete the square:
y = -3x² - 5x + 1
<u> -1 </u> <u> -1 </u>
y - 1 = -3x² - 5x
y - 1 = -3(x² + 
y - 1 + -3(
) = -3(x² + + )
↑ ↓ ↑
= 
y - 1 - 
= -3(x + )²
y - 
- = -3(x + )²
y - = -3(x + )²
y = -3(x + )² +
Now, it is in the form of y = a(x - h)² + k <em>where (h, k) is the vertex</em>
Vertex = ,
