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
What values of x is expression meaningless 4x-26x-8?
-22x-8
What are two numbers whose sum is negative twenty six and product is forty?
Let the numbers be x and ythen we have x+y=-26 and xy=40So x=40/yNow x+40/x=-26so x2 + 40+26x=0or x2 +26x +40=0You could solve this with the quadratic equation but let's complete the squarex2 +26x +40=0 is the same as(x+13)2 +40-169=0(x+13)2 =129x+13= + or = Square root of 129x=-13+square root of 129 or x=-13-square root of 129So the answers are =-13+(square root 129)-13 - square root of 129Their sum is clearly -13+-13=-26and their product is 40If you need natural numbers or rational numbers, then there is no solution, however if you want any two NUMBERS, then that is the answer.
30x2 - 26x plus 4 equals 0?
Factors are (3x - 2)(10x - 2) so x = 2/3 or 1/5 Check: 30 x 4/9 - 26 x 2/3 = 120/9 - 52/3 = -12/3 = -4 OK 30 x 1/25 - 26/5 =30/25 - 26/5 = 6/5 - 26/5 = 20/5 = -4 OK 60
What is the perpendicular bisector equation of the line joining the points 7 3 and -6 1 on the Cartesian plane showing work?
Let P = (7, 3) and Q = (-6, 1) Then mid point of PQ = ((7-6)/2, (3+1)/2) = (1/2, 2) Also, gradient of PQ = (3 - 1)/(7 + 6) = 2/13 So the gradient of the perpendicular = -13/2 Therefore the required line passes through the point (1/2, 2) and has gradient -13/2 and so its equation is (y - 2) = -13/2*(x - 1/2) or 4y - 8 = -26x + 13 that is 26x + 4y - 21 = 0

(x2 + 26x +) : syntax error.x2 + 26x
What is the answer to 8x-22 equals 2x plus 2?
8x - 22 = 2x + 28x - 2x - 22 = 2x - 2x + 26x - 22 = 26x - 22 + 22 = 2+ 226x = 24x = 24/6 = 4
