15x - 10 = -9x + 2
15x +9x -10 = -9x + 9x + 2
15 x + 9x - 10 + 10 = 2 + 10
15 x + 9 x = 2 + 10
24x = 12
24x/24 = 12/24
x = 1/2
hope this helps
Either one at any given time could be equal to zero. So
x + 2 = 0
x = - 2
x - 18 = 0
x = 18
I've enclosed a graph of this so you can see that the answers I've given are the ones expected.
Those number are all powers of 10
10= 10^1
100= 10^2
1000= 10^3
and so on...
Answer:
121 and 1331
Step-by-step explanation:
Because 11x11=121 and 11x11x11=1331
