( 0,0 ) is not the solution of the first inequality y≤x² +x-4 but ( 0,0) is the solution for the second inequality y <x²+2x+1.
<h3>What is inequality?</h3>
The relation between two expressions that are not equal, employing a sign such as ≠ ‘not equal to’, > ‘greater than, or < ‘less than’
Finding the solution for the inequality is as follows:-
y ≤ x² +x-4 by putting x and y equal to 0.
0 ≤ 0 + 0 -4
0 ≤ - 4
This is incorrect so (0,0) can not be the solution for this inequality.
y < x²+2x+1.
0 < 0 + 0 + 1
0 < 1
This inequality is showing the solution for (0,0)
Therefore ( 0,0 ) is not the solution of the first inequality y≤x² +x-4 but ( 0,0) is the solution for the second inequality y <x²+2x+1.

1 foot = 12 inches
12 1/2 or 12.5 inches
18 and 3/4 or 18.75 X 12= 225
The ratio is 12.5:225 or to simplify 1:18.
Answer:
5 times
Step-by-step explanation:
If we have to determine the number of times the lights will blink at the same time, we have to find Least common multiple (L.C.M) of 5, 12, and 6 seconds.
5 = 1 x 5
12 = 1 x 2 x 2 x 3
6 = 1 x 2 x 3
The L.C.M of 5, 6, and 12 is = 2 x 2 x 3 x 5 = 60
The three lights will be turned on after 60 seconds or 1 minute.
The lights will be turned on in 1 minute 1 time
The lights will be turned on in 5 minutes (1*5) times = 5 times
