(6 - 2) - 1 = 4 - 1 = 3
6 - (2 - 1) = 6 - 1 = 5

Answer:
Function A
Step-by-step explanation:
Function A= 10x-3
Function B= -5x+25
A slope of 10 is greater than a slope of -5
4 to 7 = 4/7
5/8 is not.
12/20 = 6/10 = 3/5 . It is not equivalent.
8:14 = 4 : 7 . It is equivalent
5 to 10 = 1 to 2. It is not.
16/28 = 8/14 = 4/7. It is equivalent.
9 to 16 = 9 to 16. It is not equivalent.
So only 8:14 and 16/28 are equivalent to 4 to 7.
