ANSWER
<span>|x – 45| = 3; minimum angle: 42
======
EXPLANATION
In general, the distance between two real numbers x and y is given by |x - y|.
Therefore, the distance between the launch angle, x, and 45 degrees is
|x - 45|
"Within three degrees" means the maximum and minimum angles are when the distance between x and 45 is 3 degrees. We set the distance to equal 3:
|x - 45| = 3
The minimum angle can be found using subtraction. 45 less than 3 is 42 degrees, so the minimum angle is 42 degrees.
42 degrees is within 3 degrees of 45 degrees. If we added 45, that would get us the maximum angle.</span>

Answer:
Let the breadth is x, then the length is 3x.
<u>The area is:</u>
<u>The breadth is decreased by 2 m: </u>
<u>The length is increased by 4m: </u>
<u>The area is now:</u>
- (x - 2)(3x + 4) = 3x² - 1/3(3x²)
- 3x² + 4x - 6x - 8 = 2x²
- x² - 2x - 8 = 0
- x² - 2x + 1 = 9
- (x - 1)² = 3²
- x - 1 = 3
- x = 4
The breadth was 4 m and the length 12 m

Step-by-step explanation:
The linear equation that represent the left balance of sanjaya’s y after visiting x number of days is:
y = 10x + 500.
<h3>What is a linear function?</h3>
A linear function is modeled by:
y = mx + b
In which:
- m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.
From the data given, we have that:
- The y-intercept is of 500.
Hence the balance is given as follows:
y = 10x + 500.
