3 times the square of a non zero number is equal to 12 times the number. what is the number?

1 answer:

8 0

Let the number be x, then we have:-

3√x = 12x
squaring both sides:-
9x = 144x^2
144x^2 - 9x = 0
9x( 16x - 1) = 0
16x - 1 = 0 so x = 1/16 answer

nignag [31]

Answer:

Step-by-step explanation:

Given Expression:

(4 x 9 - 21) \ 3+6^2

Multiply 4 and 9 to get 36.

36 - 21 / 3 + 6^2

Subtract 21 from 36 to get 15.

15/3 + 6^2

Divide 15 by 3 to get 5.

5+6^2

Calculate 6 to the power of 2 and get 36.

5+36

Add 5 and 36 to get 41.

The row-echelon form of the augmented matrix of a system of equations is given. Find the solution of the system.

Zepler [3.9K]

Answer:

option-C

Step-by-step explanation:

We are given row-echelon form

So, we can write equation from matrix as

$x-5z=-3$

$y-4z=-5$

Let's assume

$z=t$

now, we can find x and y

$x-5t=-3$

$x=5t-3$

$y-4t=-5$

$y=4t-5$

so, we get solutions as

$x=5t-3$

$y=4t-5$

$z=t$

where t can be any real numbers

For which independent value do the equations generate the same dependent value?

nalin [4]

Answer:

$x = - 3$

Step-by-step explanation:

The equations given are:

$y_1=6x+10$

$y_2=4x+4$

For the equations to generate the same independent value, then

$y_1=y_2$

This implies that:

$6x+10 = 4x + 4$

Group similar terms to get:

$6x - 4x = 4 - 10$

Simplify to get:

$2x = - 6$

$x = - 3$
