Y = 12x + 115....where x is the number of hrs and y is the number of fans
an order for 500 fans...
500 = 12x + 115
500 - 115 = 12x
385 = 12x
385/12 = x
32.08 rounds to 32.1 <=== it would take 32.1 hrs
Answer:
Option D.
Step-by-step explanation:
It is given that triangle ABC reflected in the y axes so that the image of triangle ABC is triangle A'B'C'.
Let A(a,b) and B(c,d). So, after reflection A'(-a,b) and B'(-c,d).
Using distance formula,
So,
We know that reflection is rigid transformation, it means figure and its image must be congruent.
If triangle ABC is read clockwise, then after reflection triangle A'B"C' is read anticlockwise.
Since statements I, II and IV are true, therefore the correct option is D.
