What is a rational number? By definition, a rational number can be represented as the fraction of two integers.
The goal is to find three fractions in the form
between
and
.
.
At this moment, there doesn't seems to be a number that could fit. The question is asking for three of these numbers. Multiple the numerator and the denominator by a number greater than three (e.g., five) to obtain
.
Since
and
can be any integers, let
.
.
.
Possible values of
are 26, 27, and 28. That corresponds to the fractions
,
, and
.
These are all rational numbers for they are fractions of integers.
The coordinates of vertex d is (-3, -4)
-3 • (5x + 2y = 7)
-15x - 6y = -21
-2x + 6y = 9
__________
-17x = -12
x = 12/17
5(12/17) + 2y = 7
2y = 7 - 60/17
2y = 3.47
y = 1.735
