Answer:
The transformation is (y,-x)
Step-by-step explanation:
To know the mapping notation, we need to know the coordinates of the image and the pre-image
For the pre-image, we have;
A(3,8)
B(6,8)
C(6,2)
For the image, we have
A’( 8,-3)
B’ (8,-6)
C’ (2,-6)
So let us try and get the transformation from the coordinates
We can see that this is;
(x,y) to (y,-x)
Answer:
I do believe it is B
Step-by-step explanation:
The answer is a because it’s showing that he spends 3.75$ on each sheet of paper and x represents how many he can buy. It also shows that it can be less or equal to 20$
Step-by-step explanation:
x/5 + 7 = 16
x/5 = 16 - 7
x/5 = 9
x = 9×5
= 45
