The graph of an inequality in two variables is the set of points that represents all solutions to the inequality.

A linear inequality divides the coordinate plane into two halves by a boundary line where one half represents the solutions of the inequality. The boundary line is dashed for > and < and solid for ≤ and ≥.A way to solve a linear system algebraically is to use the substitution method.

The graphs of equations within a system can tell us how many solutions exist for Infinite Solutions. If the graphs of the equations intersect, then there is one solution that is true for Looking at the graph does not tell us exactly where that point is, but we don't So a system made of two intersecting lines has one solution.
Two equations that have the same solution are called equivalent equations e.g. The addition property of equality tells us that adding the same number to. We can also use this example with the pieces of wood to explain the are equal as well.

Sloane kicked a soccer ball off the ground at a speed of 36 feet per second. the height of the ball can be represented by the fu

deff fn [24]

The total time in seconds the ball will take to travel before returning the ground is 2.25 seconds.

<h3>What is factorisation?</h3>

The breaking or breakdown of an entity (such as an integer, a matrices, or a polynomials) into a products of another unit, or factors, whose multiplication results in the original number, matrix, etc., is known as factorisation or factoring in mathematics.

Calculation for the time;

Let 't' be the time in second the ball will travel.

Let H(t) be the total height travelled by the ball.

The equation of the height is given as

$H(t)=-16 t^{2}+36 t$
