Answer:
B. a reflection across X axis and then a dilation by a scale factor of 1.5
Step-by-step explanation:
As clear from the graph all the coordinates of image 2 are 1.5 times of image 1 so shape 2 is dilated by the scale factor 1.5.
It is evident from the graph that lines AO and A"O"are parallel to each other so shape 2 is the reflection of shape 1.
Now we calculate the magnitude of line AB
m1 = (y2-y1)/(x2-x1)
=(-3+6)/(-4.5=9)
=3/4.5
=1/1.5
=2/3
Next we calculate magnitude m2 of A"B"
m2= (2-4) /(-3+6)
=(-2/3)
Then we know Tan(180-∅) = -tan∅
similarly if m1=(-m2)
then the one line having magnitude m2 is the rotated image through X axis by 180° of the line having magnitude m1.
So the answer is B.
She spends 1/4 of her day at school, this would be 8 hours out of 24 hours. which would be 8/24=1/4. therefore she spends 14 hours with her friends (3/4)

Hi!
The answer is B. Linear function.
A linear function is when the change in <em>y </em>and <em>x</em><em> </em>is constant. For example, let's make some <em>x</em> and <em>y</em> values.
x 1, 2, 3, 4, 5
y 2, 4, 6, 8, 10
When <em>x</em> increases by 1, <em>y</em> increases by 2. The change in <em>x</em> and <em>y </em>is constant, therefore, that is a linear function.
x 6, 9, 13, 26
y 3, 5, 10, 11
There is no pattern in those numbers, therefore this is not a linear function.
Hope this helps! :)
