Ok so....since the submarine is already 450 feet below sea level and its descending 300 feet descending means going down so what you do is add 450 plus 300 and get your answer which is 750! It's new position is 750 feet:) HOPED THIS HELPED HAVE A BLESSED DAY!!
ANSWER: 3/20 /=Fraction Sign
20-14=6
6-3=3
<span>8(x+3) =9+4x
8x + 24 = 9 + 4x
4x = - 15
x = -15/4
x = - 3.75</span>
Answer:
Option (B)
Step-by-step explanation:
Vertex of the given parabola → (0, 4)
Equation of the parabola with vertex (0, 4)
y = (x- 0)² + 4
y = x² + 4
Domain of this function is x < 2
Therefore, y = x² + 4 x < 2
Slope 'm' of the line passing through (4, 0) and (2, 2),
m =
=
= -1
Equation of the line passing through (4, 0) and slope 'm' = -1
y - 0 = (-1)(x - 4)
y = -x + 4
Domain : x ≥ 2
Therefore, function will be, y = -x + 4 x ≥ 2
y = x² + 4 x < 2
-x + 4 x ≥ 2
Option (B) will be the answer.
