3 = -3x + 4
-1 = -3x
1/3 = x
15 kilometers = 15,000 meters
15,000/600 = 25
So there will be a total of 25 water stations.
All you have to do is add them. So using the number line by looking at the -3 mark and find the -5 mark. Then you just add them together and you have your answer of -8!!
Answer:
f(1) = 8
Step-by-step explanation:
Step 1: Define
f(x) = 7(x - 1) + 8
f(1) = x = 1
Step 2: Substitute and evaluate
f(1) = 7(1 - 1) + 8
f(1) = 7(0) + 8
f(1) = 8
