We use the multiples of 9 and 15.
9:9,18,27,36,45,54,63,73,81,90,99,108,117,126,135
15:15,30,45,60,75,90,105,120,135
The first common multiple in this case it is 135 is the answer as they asked in how many secnds the two neon lights blink together again
Answer:
Q=2
Step-by-step explanation:
hello :
the solution to the system is
{(x,y) : x-3y=4} means infinty solution
X-3y=4
....(*)
Qx-6y=8....(**)
multiply (*) by -2
-2x+6y = -8 (***)
add (*) and (***) : (Q-2)x =0
this ie true for reals x when Q=2
Answer:
(5,0) and (5,-2)
Step-by-step explanation:
we know that
If two points are on the line x=5, then the x-coordinates of the points must be equal to 5
therefore
The coordinates of two points that are on the line x=5 are
(5,0) and (5,-2)
I believe x is 0 because if we assume y and x are 0 then 0=0 and 0= 5 x 0
