What does it mean for a ordered pair to be a solution to a linear equation?
An ordered pair is a solution only of a linear equation in two variables - not any linear equation. Often the variables are denoted by x and y. If the first of the ordered pair is substituted for x in the equation, and the second for y, then the equation represents a true statement.
How do I convert 0.666666667 into a fraction?
Assuming you mean it repeats indefinitely, you call your number "x", and write:x = 0.66666...10x = 6.66666...You subtract the first equation from the second, then solve the resulting equation for "x".Note: In other cases, if two digits repeat, you multiply by 100 to get the second equation; if three digits repeat, you multiply by 1000, etc.
Math tell whether the ordered pair is a solution of the equation?
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.
Two numbers that when added equal 70 and when multiplied equal 1225?
35 and 35.The solution is first let X and Y be the two unknown numbers.Then X + Y = 70 and X multiplied by Y equals 1225.Simplifying the first equation and substituted to the second equation it will becomeX to the power of two subtracted by 70X and added by 1225, and then simplifying by quadratic equation then it will come up of an answer of 35..

In the equation x squared plus 20 what is the second term?
Without an equality sign the given two terms of an expression can't be considered to be an equation.
If the ordered pair (3-2) satisfies one of the two linear equations in a system how can you tell whether the point satisfies the other equation of the system?
Substitute the values for the two variables in the second equation. If the resulting equation is true then the point satisfies the second equation and if not, it does not.

How do you solve -7p two to the second power negative 2p to the third power plus 5p?
-7p2 -2p3 + 5 is an expression, not an equation or inequality. An expression cannot be solved
How do you solve a simultaneous equation with 3 variables?
You cannot have a simultaneous equation: you must have 2 or more equations for there to be any simultaneity.The simplest method to solve them is to invert the matrix of coefficients but this requires you to know matrix algebra and the question suggests tha you are not that advanced.In that case, express any one of the variables in terms of the other two. Substitute the resulting expression in the other equation(s). Repeat until you have only one variable. Find its value and substitute in the previous equation. That will then enable you to find a second variable. And so on.
Is 2x to the second power-3 a linear eqation?
No because without an equality sign the given expression can't be considered to be an equation.
What are the components of a formula called?
The Reactants are the first part of a chemical equation and the Products are the second part of a chemical equation.
Would the cross section of a satellite dish be modeled by a linear or a quadratic equation?
The satellite dish is a parabolic reflector. A parabola cannot be modeled by a linear equation because a linear equation is one that graphs as a straight line. It takes a second degree expression to plot it, and that means a quadratic equation.
How do you turn 4.66666667 into a mixed number?
I will assume the "6" continues indefinitely.You call your number "x", and then: 10x = 46.66666... x = 4.66666... You subtract the second equation from the first, then solve the resulting equation for "x".
