The negative solutions are often discard because they have no real meaning in the real world, for example, you can not have -6 apples, it just doesn't make sense.
Because in real world problems, you cannot have answers such as "-3 people", "-4.56 minutes", "a shoe size of -9" etc... It is not logical.
It is an expression and if it contains an equality sign then it is an equation.
The question contains an algebraic expression but, since there is no equality sign, there is no equation to solve.
If the lines intersect, then the intersection point is the solution of the system. If the lines coincide, then there are infinite number of the solutions for the system. If the lines are parallel, there is no solution for the system.
No verse contains this.
Because in real world problems, you cannot have answers such as "-3 people", "-4.56 minutes", "a shoe size of -9" etc... It is not logical.
An expression which contains polynomials in both the numerator and denominator.
rational expression

Saturated.
The usage of polynomials in real life include mathematical models for the stock market, roller coaster designs, rocket trajectories, and in engineering for high and machine designs. A polynomial is a mathematical expression that contains exponents, variables, and constants.
this is because isotonic solutions are fluids that contains the same concentration of solutes as plasma in human..(*_*) that's what i think..._pinkay
Because these solutions contains electrically charged particles - ions.
Water in oceans always contains solutes.
The difference between sodium chloride and ammonia chloride solutions is the ions present. Both solutions contain chloride ions. However, the first solution contains sodium cations whereas the second solution contains ammonium cations.
dilute .......................................... If you are using A+ ,, The answer is Concentrated...
It is an expression and if it contains an equality sign then it is an equation.
