How do you know when an equations has infinitly many solutions?

An equation must have 1, 0, or infinitely many solutions. So if you find 1 and there is another, you have know it has infinitely many. For example. 0x+2=2 I solve this and the equations become 0x=0 Now, 1 is a solutions, but so is 2. I now know there are infinitely many. How about 0x+2=3. No solution and 2x+2=4, has one solution. I put those two here so you might try other numbers and see that they have no solutions and one solution. A special type of equation known as an identity is an equation that holds for all numbers. This means it has infinitely many solutions.


How many ounces of the 50 percent alcohol solution should be mixed with the 1 percent alcohol solution to make 8 oz of the 20 percent alcohol solution?

Let x = ounces of 50% solution, and y = ounces of 1% solution. So that we have: 0.5x + 0.01y = 8(0.2) which is a linear equation in two variables, meaning there are infinitely many choices of mixing those solutions.

What is the answer to y equals X plus 3?

There is no "the" answer. y = X + 3 is the equation of a line. There are infinitely many points on the line and the coordinates of each one of those points is a solution (or answer) to y = X + 3.


How do you determine the rule of a sequence?

It is impossible. Given any set of n numbers, it is easy to find infinitely many polynomials of order n that can be used as a rule for those numbers. In addition, there are non-polynomial solutions. Short of reading the mind of the person who posed the question, there is no way of determining which of the infinitely many solutions is the "correct" one. The best that you can do is Occam's test: go for the simplest solution. For example, what is the rule for the sequence 10, 20, 30, 40, 50? Is it t(n) = 10*n? Why not t(n) = (n^5 - 15*n^4 + 85*n^3 - 225*n^2 + 334*n - 120)/6 ? For n = 1 , 2, 3, 4, 5 they give the same result: the sequence for which you are seeking a rule. Mathematically, both answers are equally valid.

Why glucose solution cannot conduct electricity?

Glucose does not dissociate into charged ions in water solution, and the only water solutions with high conductivity are those with substantial concentrations of charged ions, such as the solutions of most salts, acids, and bases.


How can pH of a solution be tested?

By dissolving the pH solution a colour change will occur in the solution that should be tested.Compairing the colour of solution to the colours marked on of pH chart we can find out if the solution we tested is of alkaline nature or of acidic nature or neutral.Solutions of pH7are neutral solutions.Solutions below pH7 are acidic solutions and those above pH7 are alkaline solutions.


A solution in which the concentration of a solute is the maximum possible under existing conditions is said to be?

When a solution has accepted as much solute as is possible at a given temperature, the solution is said to be saturated. Under certain conditions, saturated solutions can be concentrated to give supersaturated solutions. Supersaturated solutions are those which possess more of a solute than normally dissolves in a solvent at a given temperature.


Is candle a colloid If yes what type of colloid is it?

No it is not a colloid. Colloid is a kind of solution in which the size of solute particles is intermediate between those in true solutions and those in suspension.


Why give an isotonic solution?

When comparing solutions, those that have the same concentration are isotonic. One that is more concentrated is hypertonic; less concentrated is hypotonic.
