Answer:

Step-by-step explanation:
Let first number be x and another number is y.
A rational number is a fraction that can be expressed in the form of x/y.
A rational number between x and y is given by :

So,
If x and y are two rational numbers such that x < y , then
is a rational number in between x and y.
It might be:
y=2x+6+2x-8 (times out the brackets)
y=4x-2
y intercept=-2
Solution:
If the <u>numerator</u> and the <u>denominator</u> have like bases in exponents, then the <u>exponents</u> subtract.
- =>

Thus, 7b is the simplified expression.
