-4x/5≥1/10
-8x≥1
x≤-1/8
x∈(-∞;-1/8]
This is an iteration method for finding the square root.
The ? is also your first initial guess.
? = 10.5
The iteration formula for the square root is actually.
√n = (x + n/x)÷2.
Where x is your guess.
Answer:
(-1,-1) and (4.1).
1+1
slope of the line: m= ------- = 2/5
4+1
the slope of the perpendicular line: -5/2 and point (-1,3)
(y-3) = -5/2(x+1)
The answer should be C :) in order for there to be a function, first rule is the x number cannot repeat
