Answer:
x=
3
/7
or x=
−1
/4
Step-by-step explanation:
The polynomial for the perimeter starts from the formula for the perimeter of a rectangle as written below:
Perimeter = 2L + 2W = 2( L + W)
Perimeter = 2(4A + 3B + 3A - 2B)
Perimeter = 2(7A - B)
Let perimeter be P,
P = 14A - 2B --> this would be the polynomial
Let's substitute A=12 to the polynomial:
P = 14(12) - 2B = 168 - 2B
To determine the minimum P, set it to 0.0001.
0.0001 = 168 - 2B
B = 83.999 or 84
Thus, the minimum perimeter is achieved if the value of B approached to 84.
1. Slope=9
2. x-intercept = 7/9 = 0.77778
3. y-intercept = 7/-1= -7.00000
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation: 9*X-Y-(7)=0
