Answer:
(0.5 -2.5)
Step-by-step explanation:
B is at (1, -5). A dilation by 0.5 means that these coordinates are multiplied by 0.5 each.
So 0.5(1) then 0.5(-5) = (0.5, -2.5)
Identify the transformation that was applied to this letter.
D. Rotation about the origin
Answer:
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
x² + 32² = 48²
x² + 1024 = 2304 ( subtract 1024 from both sides )
x² = 1280 ( take the square root of both sides )
x =

= 16
→ C
check by plugging into both equations
-8+4(3)=4
-8+12=4
4=4
-8+3(3)=1
-8+9=1
1=1
