A quadratic always has two solutions. They could be two real number solutions (the parabola crosses the x-axis in two places), one real number double solution (the parabola just touches the x-axis in one spot) to two complex (imaginary) solutions where the parabola doesn't cross the x-axis.

Please give me brainliest

Answer:

Option (3)

Step-by-step explanation:

In a right triangle,

Cosine rule → $cos(\theta)=\frac{\text{Adjacent side}}{\text{Hypotenuse}}$

Sine rule → $sin(\theta)=\frac{\text{Opposite side}}{\text{Hypotenuse}}$

In the given triangle,

By cosine rule,

$cos(h)=\frac{\text{Adjacent side}}{\text{Hypotenuse}}$

$cos(h)=\frac{z}{x}$

Or cos(h°) = z ÷ x

Therefore, Option (3) will be the answer.

Answer:

$\left[\begin{array}{cc|c}1&0&2\\0&2&2\end{array}\right]$

Step-by-step explanation:

The system of equations can be written in standard form as ...

x + 0y = 2

0x +2y = 2

The augmented matrix representation of these is ...

$\left[\begin{array}{cc|c}1&0&2\\0&2&2\end{array}\right]$
