x-11=13, x-11+11 = 13+11, x=24 No, 28 is not the solution to the equation
Substitute the value found back into the equation, evaluate the expressions and see if the resulting equation is true.
The expression "-y - x - 4" does not represent a solution but rather a linear expression. To determine if it represents a solution to an equation, it would need to be set equal to something (e.g., "-y - x - 4 = 0"). If you are asking whether it can be solved for a specific value, please provide more context or the equation related to it.
To determine if ( x^3 ) is a solution of the equation ( 3x - 54x = 0 ), we first simplify the equation. The left side simplifies to ( -51x = 0 ), which implies ( x = 0 ) is the only solution. Since ( x^3 ) is not equal to ( 0 ) for any ( x ) other than ( 0 ), ( x^3 ) is not a solution to the equation.
To determine if an equation is balanced, compare the number of each type of atom on the reactant side to the product side. Make sure there is an equal number of each type of atom on both sides of the equation. If the number of atoms is balanced, the equation is balanced.
An equation has an equal sign, which means that we know what the variable is equal to :)
To determine if (2, -3) is a solution of the equation ( x + 5y = 4 ), we substitute ( x = 2 ) and ( y = -3 ) into the equation. This gives us ( 2 + 5(-3) = 2 - 15 = -13 ), which does not equal 4. Therefore, (2, -3) is not a solution of the equation.
You can determine if a solution is hypotonic, hypertonic, or isotonic by comparing the concentration of solutes in the solution to the concentration of solutes in the surrounding environment. If the solution has a lower concentration of solutes than the surrounding environment, it is hypotonic. If the solution has a higher concentration of solutes, it is hypertonic. If the concentrations are equal, the solution is isotonic.
Yes, when the inequality has a less that or equal to sign, or a greater than sign or equal to sign, then the equal sign can be replaced and get a solution that is common to both the equation and the inequality. There can also be other solutions to the inequality, where as the solution for the equation will be a valid one.
The idea is to replace one variable in the equation by the first number in the ordered pair, the other variable with the second number in the ordered pair, do the calculations, and see whether the resulting expressions are indeed equal.
9x2-810 is not an equation. It has to be equal to something to be an equation. Therefore it cannot be solved.
One can determine if a solution is hypertonic, hypotonic, or isotonic by comparing the concentration of solutes in the solution to the concentration of solutes in the surrounding environment. If the solution has a higher concentration of solutes than the surrounding environment, it is hypertonic. If the solution has a lower concentration of solutes, it is hypotonic. If the concentrations are equal, it is isotonic.
