Lines with no solution are parallel lines....parallel lines will contain the same slope, but different y intercepts.
y = -2x + 3/2....slope (m) = -2 and y int (b) = 3/2
so the line we need will have a slope of -2, but can have any y int EXCEPT 3/2.
m = -2, and b = -1/3 is parallel, no solution
m = -2 and b = -2/3...parallel, no solution
The probability that the digits display a palindrome = 19/240 Ans.
As we know the total no. of possible hours = 12
Total number of possible minutes= 60
Therefore, total no. of possible times that can be shown are = 12
Since total no. of Palindromes possible per hour for the nine hours 1 through 9 = 6
No. of palindromes per hour from 10 through 12 = 1
Therefore, total no of palindromes = (6*9) + 3 = 57
Probability that the digits display a palindrome = 57/720 = 19/240
The value of x is a number :)
-4.6(2.2x+3y=15.25) = -10.12x - 13.8y = -70.15
2.2(4.6x+2.1y=18.325) = 10.12x - 4.62y = 40.315
simplify
-4.62y = -29.835
divide both sides by -4.62 to isolate y
y= 6.46
2.2x + 3 (6.46) = 15.25
2.2x + 19.38 = 15.25
subtract 19.38 to both sides
2.2x = -4.3
divide 2.2 to both sides
x= -1.95
I hope that this helped :)
