If x represents an integer how would you express its negative
1 answer:
Answer:
Step-by-step explanation:
It is important to remember that:
- Integers contains the positive numbers (+), negative numbers (-) and zero.
- The numbers greater than zero are Positive Integers.
- The numbers less than zero are Negative integers.
- An integer and its opposite have the same distance from zero, but they are located on opposite sides of the number line.
In this case we know that is a Positive Integer, therefore, based on the information mentioned before, we can say that its negative (or its opposite) is:

Given:
s is inversely proportional to t.
When s = 0.5, t = 7.
To find:
The value of s when t=0.8.
Solution:
s is inversely proportional to t.
...(i)
Where, k is the constant of proportionality.
Putting s=0.5 and t=7, we get
Putting k=3.5 in (i), we get
This is the equation of proportionality.
Putting t=0.8, we get
Therefore, the value of s is 4.375 when t=0.8.
Answer: 8
Step-by-step explanation:
Since AB is a tangent, angle CAB is a right angle. Thus, by the Pythagorean theorem,
