(5, -1)(10, 2) are solutions to this equation
- f(8) replaces x, so replace all values of x within the equation with 8
- f(8) = 1/2^2 - (1/4(8)+3))
- f(8) = 1/2^2 - (5)
- f(8) = .25 - 5
- f(8) = -4.75 (or -4 3/4)
Answer:12, 7
Step-by-step explanation:Using the process of elimination, I went through each number and subtracted five and added it until I got 12 and 7.

Step-by-step explanation:
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
