Which classification best describes the following system of equations? 3x+6y-12z=36 x=2y-4z=12 4x+8y-16z=48 inconsistent and dep
Viktor [21]

<u>Answer:</u>

Consistent and dependent

<u>Step-by-step explanation:</u>

We are given the following equation:

1. 3x+6y-12z=36

2. x+2y-4z=12

3. 4x+8y-16z=48

For equation 1 and 3, if we take out the common factor (3 and 4 respectively) out of it then we are left with x+2y-4z=12 which is the same as the equation number 2.

There is at least one set of the values for the unknowns that satisfies every equation in the system and since there is one solution for each of these equations, this system of equations is consistent and dependent.

Divide the 30x40 rectangle into 10 by 10 squares of 100
kolbaska11 [484]

Answer:

12 squares

Step-by-step explanation:

Data provided:

Dimension of the rectangle = 30 × 40

Area of the rectangle = 30 × 40 = 1200

Dimension of the area to be divided = 10 × 10

Thus,

Area of the square to be divided into = 100

Therefore,

The number of square in which it can be divided

= \frac{\textup{Total area of the rectangle}}{\textup{Area of the square}}

= \frac{\textup{1200}}{\textup{100}}

= 12

Hence,

It can be divided in 12 squares

What is the simplified form of the following expression? Assume x not-equals 0. RootIndex 5 StartRoot StartFraction 10 x Over 3
SVEN [57.7K]

Answer:

  \dfrac{\sqrt[5]{810x^3}}{3x}

Step-by-step explanation:

As a rule, the "simplified form" means there are no fractions under a radical.

  \sqrt[5]{\dfrac{10x}{3x^3}}=\sqrt[5]{\dfrac{10x(3^4x^2)}{3x^3(3^4x^2)}}=\sqrt[5]{\dfrac{810x^3}{(3x)^5}}=\boxed{\dfrac{\sqrt[5]{810x^3}}{3x}}

How many extraneous solutions does the equation below have?
Anna71 [15]

Answer:

We can say that the given equation has no extraneous solutions.

The correct option is A.) 0

Step-by-step explanation:

the given equation is \frac{9}{n^{2} +1} = \frac{n+3}{4}

this equals to 36 = (n^{2} +1)(n+3) = n^{3} + 3n^{2} + n + 3

therefore n^{3} +3n^{2} +n+3 = 36 \hspace{0.3cm}\Rightarrow \hspace{0.3cm}n^{3} +3n^{2} +n-33=0

Solving the equation through Newton-Raphson method we get n  \approx  2.3845.

We can say that the given equation has no extraneous solutions.
