Answer:


Step-by-step explanation:
Let x and y are the two positive real numbers
product of two numbers is 21


The sum of the two numbers is f(x) =x+y
Replace y with 21/x

we need to find smallest possible sum , so we take derivative using power rule

when sum is minimum then the derivative is equal to 0


multiply both sides by x^2


Take square root on both sides




Answer:
y=1.4x+6.8
Step-by-step explanation:
(-2;4) (-7;-3)
4=-2k+b
-3=-7k+b
7=5k
k=1.4
-2.8+b=4
b=6.8
I already know k and b so I can write an equation.
y=1.4x+6.8
Answer:
the answer will be -0.125
