Which best explains why the equation 4x 5 4x - 1 has no solutions?
I think this might read "4x+5 = 4x-1". Subtracting 4x from both sides cannot upset the equality, and then you have +5 = -1, which is nonsense. One moral of this is "make sure your equation makes sense, and actually includes an = sign."
WHAT IS 3Y plus 4X equals 7?
It's the equation of a straight line. Every point on the line is a solution to the equation. There are an infinite number of them.
If 16 less than four times a number is 64 what is the number?
4x - 16 = 64Add 16 to each side of the equation:4x = 80Divide each side by 4:x = 20
Seven less than four times a number equals 13?
Let the unknown number be x: 4x-7 = 13 Moving -7 to the other side of the equation changes it to +7: 4x = 13+7 4x = 20 Divide both sides of the equation by 4 to find the value of x: x = 5
One number is 4 times another The sum of the two numbers is -15 What is the value of the smaller number?

The Square of a number is 5 more than 4 times the number. Find the number that makes the sentence true.?
This is a quadratic equation which will have two solutions: X2 = 4x+5 Rearrange the equation: x2-4x-5 = 0 Factor the equation: (x+1)(x-5) = 0 So the solutions are: x = -1 or x = 5

What is a line parallel to y equals -4x plus 5?
The equation of such a line is [ Y = -4x plus any number].
What is the answer to -4x 8?
The answer is the number that 'x' must be in order to make the equation true.You said that-4x = 8Now, watch carefully, as I divide each side of the equation by -4 :x = -2
What are coordinates for -4x plus 9y equals 0?
-4x + 9y = 0 is the equation of a line in the Cartesian plane and the coordinates of any of the infinite number of points on that line will satisfy the equation.
How do you solve x-3 plus 4x?
Restate the question: Simplify: (x-3) + 4x(x-3) + 4x = x - 3 + 4x= x + 4x -3= 5x -3=======Answer 1:x - 3 + 4xThat expression is not an equation. It's just a number. The number dependson what the value of 'x' happens to be at the moment, and if 'x' changes, then(x - 3 + 4x) immediately changes. Without an equation, there's no "solution".Your expression would be an equation if there were an 'equals' sign ( = )anywhere in it.
Thrice a number is equal to six more than four times the number?
IN equation form, when the number is x: 3x = 6 + 4x 3x - 4x = 6 -x = 6
The quadratic term in 6x2 - 4x plus 25 is 6x2?
the equation 6x^2 - 4x + 25 is a quadratic equation due to the 6x^2 term. Whatever number on the x squared term changes it to a quadratic equation if you were to get rid of the 6x^2 then the equation would simply be -4x+25 making it simply a linear equation. when ever you have an x raised to 2 that term is the quadratic term in the equation.
Twelve more than four times a number is four what is the number?
Let the unknown number be x: 4x+12 = 4 4x = 4-12 4x = -8 Divide both sides of the equation by 4 to find the vlue of x: x = -2
WHAT IS 3Y plus 4X equals 7?
It's the equation of a straight line. Every point on the line is a solution to the equation. There are an infinite number of them.
What does coefficients of a quadratic equation mean?
A coefficient is the number before the variable (e.g. the 3 in 3x, or the 22 in 22x^2). For example, in the following quadratic equation, the coefficient to x is 4, and the coefficient to y is 12. 4x^2+12y+4 Remember that a number preceded by a ^ is a power, i.e 4x^2 is 4x squared.
If 16 less than four times a number is 64 what is the number?
4x - 16 = 64Add 16 to each side of the equation:4x = 80Divide each side by 4:x = 20
