The quadratic equation provides solutions for the generalized equation ax2 + bx + c = 0. The solution(s) are (-b +/- square root ( b2 - 4ac)) / 2a. Plugging in a=1, b=3, and c=-15 (from x2 + 3x -15 = 0) you get... (-3 +/- square root (32 - 4(1)(-15)) / 2(1) ... or ... (-3 +/- square root (9 + 60)) / 2 ... or ... (-3 +/- square root (69)) / 2 ... or ... about -3 +/- 8.3 Since 69 is positive, the square root (69) is real, at 8.3 This equation has two real roots, x=5.3 and x=-11.3 If the discriminant (b2 - 4ac) were zero, there would be one real root. If it were negative, there would be one real root and one imaginary root, i.e. a complex conjugate.
Presumably this is a simultaneous equation in the form of: 3r-4s = 0 2r+5s = 23 Multiply all the terms in the top equation by 2 and in the bottom equation by 3: 6r-8s = 0 6r+15s = 69 Subtract the bottom equation from the top equation: -23s = -69 Divide both sides by -23 to find the value of s remembering that a minus number divided into a minus number is equal to a plus number: s = 3 Substitute the value of s into the original equations to find the value of r: Therefore: r = 4 and s = 3
69 + 69 = 138.
69% = 69/100 = 0.69/1 = 0.69
The solution set for a linear equation in two variables comprises an infinite number of ordered pairs, and these are defined by the equation that appears in the question!
We will see. 9X - 8 = 69 - 2X add 2X to each side 2X + 9X - 8 = 69 - 2X + 2X 11X - 8 = 69 add 8 to each side 11X - 8 + 8 = 69 + 8 11X = 77 divide both sides by 11 X = 7 Now, check in original equation 9(7) - 8 = 69 - 2(7) 63 - 8 = 69 - 14 55 = 55 so, it checks and 7 is a solution here
One solution is, 4! + 67 + 2 = 24 + 69 = 93
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
The greatest common factor of 48, 69 and 120 is 3

To change 69% to decimal: 1. take out the % sign 2. divide 69 by 100 or simply put the decimal point two places to the left therefore 69% = 69/100= 0.69 in decimal

There is no "next" because points are infinitely dense.
