Answer: a

Step-by-step explanation:

$\left(\frac{f}{g} \right)(x)=\frac{f(x)}{g(x)}=\frac{\sqrt{x^{2}-1}}{\sqrt{x-1}}}=\sqrt{\frac{x^{2}-1}{x-1}}=\sqrt{\frac{(x-1)(x+1)}{x-1}}=\boxed{\sqrt{x+1}}$

Solve negative 5 over 2, the whole multiplied by x minus 5 equals negative 55.

astraxan [27]

Answer:

-24

Step-by-step explanation:

$- \frac{5}{2} x \: - 5 = 55$

Multiply through by the denominator (that is, 2)

$= 2 \times ( - \frac{5}{2} x) \: - 5(2) = 55(2)$

$= - 5x - 10 = 110$

Collect like terms

$- 5x \: = 110 +10$

$- 5x = 120$

Divide through by - 5x

$\frac{ - 5x}{ - 5} = \frac{120}{ - 5}$

$x = - 24$

The temperature in Anchorage, Alaska at 6 a.m. was 2°C. If the temperature drops 2 degrees each hour, what is the temperature in

Alchen [17]

Answer:

-14°C

Step-by-step explanation:

6 + 8 = 14

So in 24 hour time that would be 2pm

From 6am to 2pm is 8 hours

If the degrees is going down by 2 you would times the 8 by 2 because it is doubled

That = 16

Then you'll minus 16°C from the 2°C

2°C - 16°C

= -14°C

Which of the points listed is the same distance from the y-axis as the point (−1.5, 6)?

Volgvan

The complete question in the attached figure

we know that
the distance from a point to line (y-axis) is the perpendicular line against y-axis, which is the absolute value of x-coordinates

in this problem
the point (−1.5, 6)
the absolute value of x-coordinates is 1.5
hence
the distance is 1.5

therefore

the answer is
the option B) the point (1.5,-3)
