Answer :c
I think sorry if it’s not correct
The equation would be y = -5/2x - 14. Since the slope and a coordinate pair was given, I used point slope form to figure out the equation.
Work:
y - 6 = -5/2 (x+8)
y - 6 = -5/2x - 20
+ 6 +6
______________
y = -5/2x - 14
Answer: Width = 96.3cm/Length
Step-by-step explanation:
Area of a rectangle = Length multiplied by Width
Therefore Width of a rectangle is calculated Area of a rectangle divided by Length
The Width of this rectangle is therefore 96.3cm/Length
I'm sorry I'm too lazy to read all of that. However, I did get the main point. The river was going at 3 mph. Since he wanted to travel 10 miles upstream and downstream, you would have to subtract 20 by 3. This would mean he was going at a speed of 17 mph.
Step-by-step explanation:
