ANSWER

EXPLANATION
From the graph, the coordinates of Y are:

We want to find the image of this point after a dilation by a scale factor of -½ about the origin.
The rule for the dilation is :

To find the coordinates of Y', we plug the coordinates of Y.


The first choice is correct.
Answer:
x ≈ 33.1°
Step-by-step explanation:
Using the tangent ratio in the right triangle
tan x =
=
, then
x =
(

Answer:
Mala had 14 sweets at the start.
Step-by-step explanation:
7 x 2 = 14
To check, 14/2 = 7. (Dividing by 2 is the same as multiplying by 1/2)
1/3x>-2=1>3x.-2
=1>-6x
=-1/6>x
