I think it would be y= -1x but I’m not 100% sure
The answer is <span> B- y=4-1.5x
</span><span>David is rowing a boat upstream, so the river is slowing him down. Thus, the net speed is 6 mph - 2 mph = 4 mph.
Since David's speed </span><span>decreases at a rate of 1.5 miles per hour, after x hours his speed y will be:
y = 4 - 1.5 x</span>

<h3>How to graph a system of inequalities?</h3>
An inequality is a mathematical relation that compares two (2) or more integers and variables in an equation based on any of the following:
- Less than or equal to (≤).
- Greater than or equal to (≥).
Given the following system of inequalities:
y ≤ 1/3x ⇒ y - 1/3x ≤ 0
y - 2x < 4
By using an online graphing calculator, the solution to this system of inequalities are plotted in the image attached below.

Answer:
625 square feet
Step-by-step explanation:
The greatest area of a polygon with a given perimeter is that of a regular polygon. A regular rectangle is one that has all sides the same length -- a square. The side length of a square with 100 ft perimeter is 25 ft. The area of a square with such a side length is
A = (25 ft)² = 625 ft²
The maximum possible area is 625 ft².
__
In the attached, x is the length of one side. The area versus side length is plotted. The maximum is seen to be 625 ft² for a side length of 25 ft.
