By definition, let m be the slope a line, then m can be calculated by the following equation:

m=\frac{y_2-y_1}{x_2-x_1}^{}

Given that (x1, y1) and (x2, y2) are known points of the line. By reflecting all the points of the line across the line y = x

three different are rung at intervals of 36 minutes 40 minutes and 48 minutes if they were rung together at 9 a.m. at what time
Lena [83]

To find the time in which all the bells ring together, we need to find the LCM of 36,40,48.

Prime factorization of 36=2×2×3×3

Prime factorization of 40=2×2×2×5

Prime factorization of 48=2×2×2×2×3

Hence, LCM of 36,40,48=2×2×2×2×3×3×5=720 seconds.

 

720seconds=  

60

720

​

minutes=12minutes

Hence, all the bells will ring together after 12 mi
