Answer:

Step-by-step explanation:
1.The expression given is in division so when changing to multiplication the fraction is reversed.
2.Using algebra identity
.
3. Taking the common factor 5 out.
4. Finally cancelling the like terms from the numerator and denominator.
That could be expressed in two different ways ... because
there are no parentheses in your question.
One way:
Call the number ' N ' .
Nine plus the number is (9 + N)
That much times 14 is 14(9 + N) .
The other way:
Call the number ' N '.
The number times 14 is 14N
Nine plus that is 9 + 14N .
Answer:
1) f(x)<x+4
f(x)>-x-3
f(x)<5

2)2.5>0+2
2.5<0+3
2.5<0+5
