Answer:

$\frac{ \sqrt{5x} }{5x}$

Step-by-step explanation:

$\frac{1}{ \sqrt{x5} }$

$= \frac{1}{ \sqrt{5x} }$

$= \frac{1}{ \sqrt{5x} } \times \frac{ \sqrt{5x} }{ \sqrt{5x} }$

$= \frac{1 \sqrt{5x} }{ \sqrt{5x \sqrt{5x} } }$

$= \frac{\sqrt{5x} }{ \sqrt{5x \sqrt{5x} } }$

$= \frac{ \sqrt{5x} }{5x}$

I need help please!!!!

Answer:

(c) y -2 = 6/5(x -1)

Step-by-step explanation:

The equations are all in point-slope form with a slope of 6/5. The points used are (-1, -2), (-2, -1), and (1, 2). It seems point (1, 2) best matches a point on the graphed line. Choice C is the best. (In the attached graph, choice C is the red line.)

_____

<em>Additional comment</em>

The point-slope form of the equation for a line is ...

y -k = m(x -h) . . . . . . . line with slope m through point (h, k)

__

The equation might be easier to see if the point chosen were one at a grid intersection, such as (-4, -4) or (6, 8).

Can you help me with this it’s so confusing plz help me with both is this

mars1129 [50]

Answer:

First picture: -4,913

Second picture: 20.25

Step-by-step explanation:

-17^5/-17^2 = -17^3

-17 × -17 × -17 = -4913

4.5^5/4.5^3 = 4.5^2

4.5 × 4.5 = 20.25

Do you see how I had the same whole number on the top and bottom? (17 was on top and 17 was on bottom)

The exponents were those tiny numbers you saw.

Whenever you are dividing by the same whole number (-17/-17), you can subtract exponents.

When you multiply the same whole number, you can add the exponents.

Hope this helps! Best of luck :)
