What is an Inequality Equation?
Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.
Given data ,
Let the inequality relation be A
And the equation is 3x - 2 ≤ 2x + 1.
So , on simplifying the equation , we get
3x - 2 ≤ 2x + 1.
Subtracting 2x on both sides of the inequality equation , we get
x - 2 ≤ 1
Adding 2 on both sides of the inequality equation , we get
x ≤ 3
Therefore , the value of x satisfies all the numbers that are less than or equal to 3
Hence , The solution set is {x | x R, x ≤ 3}

A.6 meters
B.10 meters
C.12 meters
D.15 meters
The variables a and b are,
⇒ a = 3
⇒ b = 4
A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines relationship between one variable and another variable.
We know that;
For a hyperbola ;
⇒ x² / a² - y² / b² = c²
where, a² + b² = c²
And, The directrix is the line, y = a² / c
and, the focus is at (0, c).
Here, We have;
⇒ c = 5,
⇒ a² = 9,
So We get;
⇒ b² = 5² - 9 = 16.
Thus, We get;
⇒ a = √9 = 3
⇒ b = √16 = 4
