Let
A (0,-2) B (1,-3) C (2,-4) D ( 3,-5) E (4,-6)
using a graph tool
see the attached figure N 1
case a) exponential

see the attached figure N 2
case b) quadratic

see the attached figure N 3
case c) linear

see the attached figure N 4
case d) linear

see the attached figure N 5
therefore
the answer is
the case c) linear

I don't think when this number is added to any other rational number would produce an irrational number
But we do know that when 0.4 is added to an irrational number it would be irrational.
e.g; 0.4 + pi is irrational, etc, etc
So any other irrational number would make it irrational
Answer:
I think it's 208.8m
Step-by-step explanation:
717.8 divided by 7.4 = 97. 97 x 2 + 7.4 x 2 =208.8m
8/14, which can be reduced to 4/7 by dividing 8 by 2 and 14 by 2
So, your answer is 4/7
