Square root of 2x2 - 4x - 7 suare root 2 equals 0?
_//(2*2) - 4x - 7// * _//2// = 0 4* 12x - 7 * 122/100 = 0 28*12x * ((28*12)/122) = 0 (23/10 * x) * ((23/10 * x)/122) = 0 23/10 *x = 0 / ((23/10 *x)122) 23/10 *x = 0 23/x = 10 x = 2.3
The burns have 2 children THe sum of their ages is 23 and the product is 132 how old are the children?
X + Y = 23 XY = 132 Y = 23-x xy = x (23-x) = 23x -x2= 132 x2-23x+132 = 0 (X-11)(x-12) = 0 X = 11 Y = 12
What numbers add to -23 and multiply to 210?
187
What two numbers have a product of 24 and a sum of 23?
xy=24 and y=23-x so x(23-x)=24, which is x2-23x+24 = 0, and you solve this using the formula method to get approximately 21.95 and 1.05 If the product had been 23 and the sum 24 the equation would have factorized easily and you would have 1 and 23
What would the binary number 1011 be in decimal notation?
1011 = 1 x 23 + 0 x 22 + 1 x 2 + 1 x 1 = 11
X2 -23x equals 0?
(x^2)-23x=0 Start by factoring out an x: (x)(x)-23x=0 x(x-23)=0 Set each quantity to 0 and solve for x: x(x-23)=0 x=0 x-23=0 x-23+23=0+23 x=23 Therefore x=0, x=23
What is the answer for x in 5x-23 equals -23?
x=0
Square root of 2x2 - 4x - 7 suare root 2 equals 0?
_//(2*2) - 4x - 7// * _//2// = 0 4* 12x - 7 * 122/100 = 0 28*12x * ((28*12)/122) = 0 (23/10 * x) * ((23/10 * x)/122) = 0 23/10 *x = 0 / ((23/10 *x)122) 23/10 *x = 0 23/x = 10 x = 2.3
What number is needed to complete the square x2-23x equals 0?
(23/2)2 x2 - 23x = 0 x2 - 23x + (23/2)2 = (23/2)2 (x - 23/2)2 = (23/2)2 x - 23/2 = 23/2 x = 23/2 + 23/2 x = 23 Of course you could come to this solution much more easily by dividing the whole equation by x at the start. There really is no need to complete the square in this case: x2 - 23x = 0 x - 23 = 0 x = 23
What multiple has 23?
To get the multiples of 23, just multiply 23 x 0, 23 x 1, 23 x 2, etc. - Or, starting with zero, add 23 at a time.
The burns have 2 children THe sum of their ages is 23 and the product is 132 how old are the children?
X + Y = 23 XY = 132 Y = 23-x xy = x (23-x) = 23x -x2= 132 x2-23x+132 = 0 (X-11)(x-12) = 0 X = 11 Y = 12
If a zero is in the equation does the answer have a zero?
no, eg. 409 x 2 = 818 19 x 0 + 23 = 23
How do you read a binary code?
similar to a base 10 number... Ex: 100100 contains 6 place values. The left most is 1 x 26-1 , the second is 0 x 25-1 , and 0 x 24-1 ,1 x 23-1 ,0 x 22-1 ,0 x 21-1 . or 1 x 25 , 0 x 24 , 0 x 23 , 1 x 22 , 0 x 21 , 1 .
What is the vertex of y equals x2-x-23?
25
What is 0 x 23 5671459087532?
It is zero because anything multiplied by 0 is zero
What is an example of a function notation?
f : x -> 3x + 2 where 0 < x <23.
What is x in the algebra puzzle 3x plus 8-31?
3x+8-31=0 Simplify it. 3x-23=0 Add 23 to both sides to get rid of the -23 3x=23 Divide both sides by 3 x=23/3 Simplfy the fraction x=9 2/3 So there we have it, x is nine and two thirds (or 9.6666...)
