Horseshoe crabs are marine and brackish water arthropods. They live primarily in and around shallow coastal waters on soft sands.
M = (y2-y1)/(x2-x1)
= (4-14)/3-1
= -10/2
= -5
Answer:
Third option
Step-by-step explanation:
We can't factor this so we need to use the quadratic formula which states that when ax² + bx + c = 0, x = (-b ± √(b² - 4ac)) / 2a. However, we notice that b (which is 6) is even, so we can use the special quadratic formula which states that when ax² + bx + c = 0 and b is even, x = (-b' ± √(b'² - ac)) / a where b' = b / 2. In this case, a = 1, b' = 3 and c = 7 so:
x = (-3 ± √(3² - 1 * 7)) / 1 = -3 ± √2
Just count, its really simple...its hard to explain using a keyboard tho...sorry i wasnt much help
