Does an equation have to contain a variable?
An equation does not need variables. 4+5=9 is an equation as is 5+W=9
What is the equation of the horizontal line that passes through the point (9-4)?
Assuming the point is (9, -4), the equation is y = -4.
Use addition or substitution to find the value of x for this set of equations 4x plus 13y equals 40 4x plus 3y equals -40?
Try elimination.4X + 13Y = 40- 1(4X + 3Y = - 40)4X + 13Y = 40- 4X - 3Y = 40-----------------------add10Y = 80Y = 8-------------find X ( top equation )4X + 13(8) = 404X + 104 = 404X = - 64X = - 16----------------------check in both equations for consistency4(- 16) + 13(8) = 40- 64 + 104 = 4040 = 40-------------top checks4(- 16) + 3(8) = - 40- 64 + 24 = - 40- 40 = - 40-------------------both check and are consistentSo, X is,- 16 ( while Y is 8 )
Is the point 39 a solution of the equation y8x-9?
The expression of y8x-9 has no solution because without an equality sign it can not be considered to be an equation.
What is the equation of the circle with center (2 -9) and radius 7?
Equation of circle: (x-2)^2 +(y+9)^2 = 49
How do you solve this equation 42 plus 4y-12 equals 13y-12-2y?
42+4y -12 = 13y -12 -2y 4y -13y+2y = 12 -12 -42 -7y = -42 y = 6
How do you factor 2y2-13y-45?
(2y + 5)(y - 9)
What is the factor of x2 - 169y2?
(x - 13y)(x + 13y)
What is 9x-3(x plus 13y)?
9x - 3(x + 13y) = 9x - 3x - 39y = 6x - 39y = 3(2x - 13y)
How do you solve for y if -2x plus 13y equals 11?
-2x+13y=11 13y=2x+11 y=2x/13 + 11/13
What is y squared plus 13y plus 40 equals 0?
If y2 + 13y = 40, then y ~ 15.55If y2 + 13y = 0, then y = -13Improved Answer:-y2+13y+40 = 0(y+5)(y+8) = 0Therefore: y = -5 and y = -8
What is the answer to -13y - 7x - 6x?
-26x
9 plus 7y-3 plus 6y?
This simplifies to 6+13y If you meant 9+7y-(3+6y) then it becomes 6+y It is not clear from the problem which you meant.
What is nine less than a number is 9?
It is an equation: n - 9 = 9It is an equation: n - 9 = 9It is an equation: n - 9 = 9It is an equation: n - 9 = 9
Divide y2 plus 13y plus 22 by y plus 2?
(y2+13y+22)/(y+2) = (y+11)
What is -13y 3?
y= -3/13​​
4y2 plus 3-13y solve quadratic formula?
If you mean: 4y^2 +3 -13y then the expression is (4y-1)(y-3) when factored
