Step-by-step explanation:
Answer:
(0, -3)
explanation:
- original coordinates of C: (0, -7)
If reflected over y axis, there will be additive inverse in x unit
use the formula: (x,y) → (−x, y)
Then if translated vertically, there will be change in y axis:
(0, -7+4) → (0, -3)
Step-by-step explanation:
just look what happened :
every term was multiplied by a factor with the value 1 (to keep the original value) but to establish a common denominator.
a/b was multiplied by d/d, and c/d was multiplied by b/b, so that the common denominator is then bd.
so, the first answer option is correct.
although I am a bit unhappy with its phrasing.
but the other options are definitely wrong.
1. 5x72+6 over 72 = 366/72
2. 8x9+3 over 9. = 75/9
I think that x^2-9 (difference of 2 squares), 216x^3 +729 (sum of 2 cubes), and the other two are none
Not entirely sure
