Step-by-step explanation:
We have xy = 28, x² + y² = 65 and x³ + y³ = 407.
Since (x + y)(x² - xy + y²) = x³ + y³,
x + y = (x³ + y³)/(x² + y² - xy)
= (407) / [(65) - (28)]
= 407 / 37
= 11.
Hence the sum of the numbers is 11.
Answer:
Answers are below
Step-by-step explanation:
Step 1: Graph the function
Step 2: Identify the type of function. This can be done by looking the exponents
Step 3: Since the exponent is 3, the function is not linear, but instead a cubic function.
