What are some hard math equations that equals 7?
How about finding the solutions of the quadratic equation: x^2-14x+49 = 0
What are math statements that contains variables?
math statements that contain variables are expressions or equations that have a letter or symbol that represents a number or value. for example, if (2+N=7), N is the variable and N=5 hope this helps
How do you solve linear equations by using elimination?
You multiply one or both equations by some constant (especially chosen for the next step), and add the two resulting equations together. Here is an example: (1) 5x + 2y = 7 (2) 2x + y = 3 Multiply equation (2) by -2; this factor was chosen to eliminate "y" from the resulting equations: (1) 5x + 2y = 7 (2) -2x -2y = -6 Add the two equations together: 3x = 1 Solve this for "x", then replace the result in any of the two original equations to solve for "y".
What equation passes through point 3 2 The equations given are y - 3 x y 3x - 7 y 2x - 4 y 4x - 2 Another difficult one. Need to know how to reach the answer if possible.?
Not sure what the equations are. please write them as y=3x+c or something like that They all run together. Then i can help you! Dr. Chuck aka math doc
What are the different types of equations and their generic formulas in algebra 2?
1. Linear Equations y= mx + b (standard form of linear equation) 2. Quadratic Equations y= ax^2+bx+c 3. Exponential Equations y= ab^x 4. Cubic Equations y=ax^3+ bx^2+cx+d 5. Quartic Equations y= ax^4+ bx^3+ cx^2+ dx+ e 6. Equation of a circle (x-h)^2+(y-k)^2= r^2 7. Constant equation y= 9 (basically y has to equal a number for it to be a constant equation). 8. Proportional equations y=kx; y= k/x, etc.
What math equations equal number 63?
As an example: 9x = 63 then x = 63/9 and so x = 7
How are math expressions and math equations different?
Math equations have an equals sign such as: 7+5=12 or 9x6=47+7 Math expressions do not have a equals sign such as: 43-27 or 8x40
What are some examples of math equations?
An equation is a series of numbers and/or variables with an equals sign to show that both sides are equal. For example: 2+5=7 7-1=5+1 2x=6
What is a system of equations that equals -3 and 7?
Systems of equations don't equal numbers.
What are some hard math equations that equals 7?
How about finding the solutions of the quadratic equation: x^2-14x+49 = 0
How do you make an equation in math?
To make an equation, you need to have an equal sign "=" and something on both sides of the equal sign. For example, the following are equations:1 + 1 = 278 - 56 * 4 = -1429 - 10 = -1The following are not equations:8 =8 + 745 + 7 (4*1) - 20

What equles 84?
There are many equations that equal 84. 14 multiplied by 6 is equal to 84. 7 multiplied by 12 is also equal to 84.
What is a math equation that equals 23?
An equation is a statement, and is never 'equal to' a number.Here are a few equations that all have the solution [x = 23] :x + 3 = 26x - 7 = 165x + 7 = x + 99x2 - 26x + 69 = 0x (26 - x) = 69
-7 plus 12?
The equation -7 plus 12 equals out to be five. This is a math problem.
