Answer:

The correct answer is, Option d.

Step-by-step explanation:

It is given a system of equation.

- 2x - 2y + 5z = 1

- 5x - 5y + 7z = 4

9x - 2y + 2z = -1

<u>To find the augmented matrix</u>

To find the augmented matrix we have to write the coefficients of the given system of equation.

- 2   - 2   5  |  1

- 5   - 5   7  |  4

 9   - 2   2  |  1

Therefore the correct answer is Option d.

What value of x would make Bl parallel to RA?
igomit [66]

Given:

Bl parallel to RA.

To find:

The value of x.

Solution:

In triangle ATR and ITB,

\angle ATR\cong \angle ITB              [Common angles]

\angle ART\cong \angle IBT              [Corresponding angle]

\triangle ATR\sim \triangle ITB              [AA property of similarity]

We know that the corresponding sides of a similar triangle are proportional. So,

\dfrac{AT}{IT}=\dfrac{AR}{IB}

\dfrac{x}{x+8}=\dfrac{12}{18}

\dfrac{x}{x+8}=\dfrac{2}{3}

On cross multiplication, we get

3(x)=2(x+8)

3x=2x+16

3x-2x=16

x=16

Therefore, the correct option is C.
