A) x² + y² = 327
B) x * y = 101
Solving equation B for y²
B) y² = 10,201 / x²
Substituting this into equation A)
x² + 10,201 / x² = 327
x^4 + 10,201 = 327x²
x^4 -327x² + 10,201 = 0
Using the quartic equation calculator: http://www.1728.org/quartic.htm
x1 = 17.090169943749476
x2 = 5.909830056250525
x1 * x2 = 101
x1 + x2 = 23
Answer:
B
Step-by-step explanation:
find slope which is -2 then plug into equation y=mx+b to find constant of 3
Divide the amount he paid by the number of hours.
$79.80/(6 hours) = $13.30/hour
