Using the table, we will see that the function is:

t(l) = 3*l

<h3>How to write the function?</h3>

Here we only have a table to work with, so we need to use that.

In the table, we can see the pairs:

t(1) = 3
t(2) = 6
t(3) = 9
t(4) = 12

So, in each new level, we just add 3 more toothpicks. Even more, we can see that the number of toothpicks is 3 times the value of l (the level) for all the cases in the table. So this is a linear function.

From that we can conclude that the function will be:

t(l) = 3*l

Is the following sentence a statement or not a statement? X and Y define a line

elixir [45]

Yes, that's a statement. Another example of a statement is "(0,0) is the origin." Something that wouldn't be considered a statement is something like "pi is a boring and confusing number."

Hope this helps!

I need to find the standard form of this equation:<br> 4y^2+40y+3x+103=0

ExtremeBDS [4]

Hi!

The standard form would be

“4y^2+40y= -3x-103”

Complete the square

Nesterboy [21]

Answer:

vertex at (1, -3)

Step-by-step explanation:

When x = 0

y² + 6y + 1 = 0

y² + 6y + = -1

y² + 6y + 9 = -1 + 9

(y + 3)² = 8 or (-y - 3)² = 8

y + 3 = √8 or -y - 3 = √8

y = - 3 +√8 or y = -3 - √8

(0, - 3 +√8) and (0, -3 - √8)

The mid point between these two is the average

y = ( - 3 + √8 + -3 - √8) / 2 = - 3

y² + 6y + 8x + 1 = 0

(-3)² + 6(-3) + 8x + 1 = 0

9 - 18 + 1 = -8x

- 8 = -8x

x = 1

An augmented matrix for a system of linear equations in x, y, and z is given. Find the solution of the system.

Angelina_Jolie [31]

Answer:

(x, y, z) = (-4, 2, 1)

Step-by-step explanation:

See the attachment for the output of a calculator that produces the reduced row-echelon form of the matrix.

The [x, y, z] result vector is the column on the right.

(x, y, z) = (-4, 2, 1)

_____

Numerous web sites are available for computing the row-reduced form of the matrix, or for solving the system of equations. Your graphing calculator will do it as well.
