Answer:
D
Step-by-step explanation:
Hi there!
We're given the equation y=-75x-50, which represents a submarine DESCENDING towards the ocean floor, where y is the depth in feet, and x is the number of minutes the submarine is descending
Since the submarine is DESCENDING, we can immediately eliminate A and C, which talk about the submarine ASCENDING
That leaves B and D
Looking at the given equation, y=-75x-50, -75 is the slope, or rate of change, and -50 is the y intercept, or the "beginning" (where the equation will "start")
Therefore, the submarine will start at -50 feet, or 50 feet below sea level
As x is the number of minutes the submarine is descending, that means that if the submarine travels 1 minute, it will descend 75 feet (-75*1=-75), at 2 minutes, it'll descend 150 feet (-75*2=-150), and so on
So that means the submarine must be descending at a rate of 75 feet per minute
Therefore D is the correct answer
Hope this helps! Good luck on your assignment :)
The translation of the given algebraic words to symbols is: C. 3(ab).
<h3>How to Translate Algebraic Words to Symbols?</h3>
The algebraic word, "triple" connotes "3 times'. "Product" means multiplication. Therefore, we would have the following translation:
Product of ab = ab
Triple of ab = 3(ab).
Therefore, the algebraic words translated to symbols is: 3(ab).

Answer:
x intercept = 0.23
y intercept = 3
Explanation:
Equation of line, y=−13x+3
At x intercept, y = 0
0=−13x+3
x = 0.23
At y intercept, x = 0
y=−13*0+3
y = 3
