Answer:

The correct option is b

Step-by-step explanation:

The given equation is

xy=-2.5

It can be written as

xy+2.5=0              .... (1)

The general forms of conic is

Ax^2+Bxy+Cy^2+Dx+Ey+F=0             .... (2)

From (1) and (2), we get

A=0,B=1,C=0,D=0,E=0,E=2.5

B^2-4AC=1-4(0)(0)=1>0

Since the value of B²- 4AC > 0, then it is hyperbola.

The formula form angle of rotation is

\tan 2\theta=\frac{B}{A-C}

\tan 2\theta=\frac{1}{0-0}

\tan 2\theta=\infty

\tan 2\theta=\tan (90^{\circ})

2\theta=90^{\circ}

\theta=45^{\circ}

The angle of rotation is 45°. Therefore the correct option is b.

Answer:

It is B. hyperbola, 45 degrees.

SteIt is p-by-step explanation:

If we rotate the standard form  x^2 - y^2 = 1 through 45 degrees we get xy = 1/2.

xy = -2.5 comes from x^2 - y^2 = -5  being rotated 45 degrees.

Solve the inequality, enter it in interval notation , 6x+3<8(8x+6)+3
garik1379 [7]

Answer:

The answer to your question is:    ( - 24 / 29, ∞ )

Step-by-step explanation:

                                             6x + 3 < 8 (8x + 6) + 3

                                             6x + 3 < 64x + 48 + 3

                                             6x + 3 < 64x + 51

                                             6x - 64x < 51 - 3

                                            - 58 x < 48

                                            x > - 48 / 58

                                            x > - 24 / 29

                                          ( - 24 / 29, ∞ )
