Which system of equations corresponds to this matrix multiplication operation

faltersainse [42]

Answer:

Option (B)

Step-by-step explanation:

$\begin{bmatrix}5 & 2 & 1\\ 7 & -5 & 2\\ -5 & 3 & 1\end{bmatrix}\times \begin{bmatrix}x\\ y\\ z\end{bmatrix}=\begin{bmatrix}16\\ 3\\ 12\end{bmatrix}$

By applying multiplication property of the matrices,

$\begin{bmatrix}(5x+2y+z)\\ (7x-5y+2z)\\(-5x+3y+z) \end{bmatrix}=\begin{bmatrix}16\\ 3\\ 12\end{bmatrix}$

Therefore, system of equations formed will be,

5x + 2y + z = 16

7x - 5y + 2z = 3

-5x + 3y + z = 12

Option (B) will be the correct option.

Two consecutive even integers have the following property. When the smaller integer is added to three times the larger integer,

polet [3.4K]

let x be the first integer
x+ 2 the second integer ( two consecutive even )

smaller integer added to three times the larger  <span>x + 3 ( x+2)
  </span>two less than five times the smaller <span>5x - 2</span>

x + 3 ( x+2) = 5x - 2

x+3x +6 = 5x -2

x=8
the first integer = 8
the second is x+2 =10

Solve for x please help !!!!!!!

exis [7]

Answer:

x ≈ 20.31

Step-by-step explanation:

By applying tangent rule in the given right triangle,

tan(55°) = $\frac{\text{Opposite side}}{\text{Adjacent side}}$

Measure of the opposite side = 29 units

Measure of the adjacent side = x

Substitute these values in the expression,

tan(55) = $\frac{29}{x}$

x = $\frac{29}{tan(55)}$

x = 20.306

x ≈ 20.31
