Which ordered pair satisfies the linear equation 2x 3y 12?
Answer. The ordered pair (3,2) is the solution to the system of equations 2x+3y=12 and 2x-y.
Which ordered pair of numbers is the solution of the system?
The solution to a system of linear equations is the ordered pair (or pairs) that satisfies all equations in the system. The solution is the ordered pair(s) common to all lines in the system when the lines are graphed. Lines that cross at a point (or points) are defined as a consistent system of equations.
Which is true about a linear equation?
A linear equation only has one or two variables. No variable in a linear equation is raised to a power greater than 1 or used as the denominator of a fraction. When you find pairs of values that make a linear equation true and plot those pairs on a coordinate grid, all of the points lie on the same line.
Which of the following is a linear equation in two variables?
An equation is said to be linear equation in two variables if it is written in the form of ax + by + c=0, where a, b & c are real numbers and the coefficients of x and y, i.e a and b respectively, are not equal to zero. For example, 10x+4y = 3 and -x+5y = 2 are linear equations in two variables.
Is 2x 3y 7 a linear function?
In particular, the set of solutions to 2x – 3y = 7 is a straight line. (This is why it’s called a linear equation.)
Is 4xy 5y 8 0 A linear equation?
it is a linear equation as its degree is 1 .
Is the equation a linear equation in two variables 4m 3n 12?
Answer: No,this is not a linear equation because linear equation have only one variable but the given equation contains two variables(m,n).
Is Y 2x a linear function?
It is LINE. A straight line, no curves. For example: y = 2x – 3 This is linear because the exponent on x is one.
How do you solve linear equation word problems?
Writing Systems of Linear Equations from Word Problems
- Understand the problem. Understand all the words used in stating the problem. Understand what you are asked to find.
- Translate the problem to an equation. Assign a variable (or variables) to represent the unknown. Clearly state what the variable represents.
- Carry out the plan and solve the problem.
How do you solve a linear equation problem?
Solving Linear Equations
- Solve: (2x + 5)/(x + 4) = 1.
- ⇒ 2x – x = 4 – 5 (Transferring positive x to the left hand side changes to negative x and again, positive 5 changes to negative 5)
- Solution:
- ⇒ 3x/3 = 9/3 (Dividing both sides by 3)
- ⇒ 5 – 2x + 2 = 12 – 4x – 2x (Removing the brackets and then simplify)
- x/2 + x/3 = x – 7.
What is the formula for a linear equation?
The standard form for linear equations in two variables is Ax+By=C. For example, 2x+3y=5 is a linear equation in standard form. When an equation is given in this form, it’s pretty easy to find both intercepts (x and y).
What is a linear equation word problem?
When writing linear equations (also called linear models) from word problems, you need to know what the x and y variables refer to, as well as what the slope and y-intercept are. Here are some tricks to help translate: The x variable. Usually, you’ll be asked to find an equation in terms of some factor.
What is linear equation in simple words?
The definition of a linear equation is an algebraic equation in which each term has an exponent of one and the graphing of the equation results in a straight line. An example of linear equation is y=mx + b.
What is the difference between linear equation and linear function?
While all linear equations produce straight lines when graphed, not all linear equations produce linear functions. In order to be a linear function, a graph must be both linear (a straight line) and a function (matching each x-value to only one y-value). is a linear equation but does not describe a function.
What is use of linear equation?
2.5 Applications of Linear Equations Identify key words and phrases, translate sentences to mathematical equations, and develop strategies to solve problems. Solve word problems involving relationships between numbers. Solve geometry problems involving perimeter.
