Answer : (8,5)
Given
K(x) =
Now we plug in each point and check whether it satisfies our equation
(-64,12)
K(-64) = = 12 so this point lie on graph
(125,3)
K(125) = = 3 so this point lie on graph
(343,1)
K(343) = = 1 so this point lie on graph
(8,5)
K(8) = = 6 so this point does not lie on graph because we got 6 instead of 5

1. Use the FOIL method (x+9)(x+9)
First, outer, inner, last
Add your like terms
2. When you add or subtract polynomials you add or subtract the like terms and then put them in order from largest to smallest exponents.
3.
4. Since it is the perimeter, we add the 3 together.
Add the like terms together:
Put them in order of exponents

Answer:
slope =
Step-by-step explanation:
calculate the slope m using the slope formula
m =
with (x₁, y₁ ) = (9, 6 ) and (x₂, y₂ ) = (4, 5 )
m = = =
1. Divide wire b in parts x and b-x.
2. Bend the b-x piece to form a triangle with side (b-x)/3
There are many ways to find the area of the equilateral triangle. One is by the formula A=
A=
Another way is apply the formula A=1/2*base*altitude,
where the altitude can be found by applying the pythagorean theorem on the triangle with hypothenuse (b-x)/3 and side (b-x)/6
3. Let x be the circumference of the circle.
so
Area of circle =
4. Let f(x)=
be the function of the sum of the areas of the triangle and circle.
5. f(x) is a minimum means f'(x)=0
f'(x)=
=0
6. So one part is
and the other part is b-
