What is the solution of the system? y=x^2 + 6x + 9
Katyanochek1 [597]

Because we have two values of x, we can set the two expressions equal to each-other.

x^2 + 6x + 9 = x + 3

Subtract x and 3 from both sides.

x^2 + 5x + 6 = 0

Now that we have all terms on one side, we can find the values of x.

Using the AC method, we can simplify this equation to (x + 2)(x + 3)

The solutions to the system of equations presented are:

<h3>x = -2, x = -3.</h3>

The number of board feet in a 16 foot long tree is approximated by the model F(d) = 0.77d^2 -- 1.32d -- 9.31 where F is the numb
Lubov Fominskaja [6]

we are given

F(d)=0.77d^2-1.32d-9.31

where

F is the number of board feet

d is the diameter (in inches) of the log

Since, we have to minimize F

so, firstly we will find it's derivative

F'(d)=0.77\times 2d-1.32\times 1-0

F'(d)=1.54d-1.32

now, we can set it to 0

and then we can solve for d

F'(d)=1.54d-1.32=0

1.54d-1.32=0

so, we get diameter as

d=\frac{6}{7}inch..............Answer

Given that f(x)=-3x+9, what is f(4)?
timurjin [86]

Answer:

F(4) = -3

Step-by-step explanation:

First, you would plug in 4 for x. PEMDAS, so you would multiply -3 and 4, giving you -12. Then add 9, which gives you -3.

a triangle with vertices at A (-1,1), B(-2,1) C(-1,4) is translated. the image of vertex A has coordinate at (3,-1) determine th
Drupady [299]
For this case we have the following vertices:
 A (-1,1) --------> A '(3, -1)
 B (-2.1)
 C (-1,4)
 We note that the translation rule is:
 (x, y) -----------> (x + 4, y-2)
 Applying the translacion rule we have:
 B (-2, 1) -----------> (-2 + 4, 1-2) ------> B '(2, -1)
 C (-1, 4) -----------> (-1 + 4, 4-2) ------> C '(3, 2)
 Answer:
 
The image of vertex B or the image of Vertex C are:
 
B '(2, -1)
 
C '(3, 2)
