The mathematical expression to represent the number of years elapsed since the disappearance of Helike until the end of the American Civil War is:
- T (years from Helike's disappearance to the end of the Civil War) = w + 373
To reach this conclusion we had to search for additional information and found that the year of the disappearance of the Greek city of Helike is -⅕ times the year the American Civil War ended.
- Helike's disappearance year = (-w / 5)
According to the previous expression, the year of Helike's disappearance is:
- Helike's disappearance year = (-1865/5) = -373
According to the previous data, it can be inferred that the expression that represents the number of years elapsed between the disappearance of the Greek city of Helike and the end of the US Civil War is:
- T = w + 373
- T = 1865 + 373
- T = 2238
Note: This question is incomplete because the is some information missing. However, I can answer it based on my prior knowledge.

Using the Pythagorean Theorem, we can tell that there is 10 units between the two points.
Answer:
A
Step-by-step explanation:
Solving for x:
-3x + 8 ≥ 14
-3x ≥ 6
x ≤ -2
Notice the sign gets reversed when you divide or multiply by a negative number.
The only option less than -2 is -3, A.
Here's a tip: on multiple choice questions, sometimes it's faster to try each answer instead of solving the equation. This can save time on tests like the SAT or ACT.
Let's try it:
-3(-3) + 8 = 9 + 8 = 17
-3(-1) + 8 = 3 + 8 = 11
-3(0) + 8 = 0 + 8 = 8
-3(3) + 8 = -9 + 8 = -1
So you can see the answer is A.
