Answer:

-7

Step-by-step explanation:

You first multiply both sides by 10 to get rid of the decimal points, we don't want them.

25x + 100 = 10x - 5

Then, you subtract 100 from both sides:

25x = 10x - 105

Then, you subtract 10x from both sides:

15x = -105

Lastly, you divide by 15 on both sides:

x = -7

So, your answer is -7 :)

Find the image of each polygon with the given vertices after a dilation centered at the origin with the given scale factor. J(2,

MAVERICK [17]

Applying a dilation centered at the origin with scale factor $k$ has the effect of multiplying both coordinates of a point by $k$ :

$(x,y)\mapsto (kx,ky)$

So, in your case, the coordinates of the points double:

$J'=(4,8),\quad K'=(8,8),\quad P'=(6,4)$

Which choice is equivalent to the quotient below shown here when x>0?

qwelly [4]

Answer:

Choice B is correct

Step-by-step explanation:

The given radical division can be expressed in the following form;

$\frac{\sqrt{16x^{3} } }{\sqrt{8x} }$

Using the properties of radical division, the expression can be expressed in the following form;

$\sqrt{\frac{16x^{3} }{8x} }=\sqrt{2x^{2} }$

Simplifying further yields;

$\sqrt{2x^{2} }=\sqrt{2}*\sqrt{x^{2} }=x\sqrt{2}$

Choice B is thus the correct alternative

Answer:

total ground and wall angle is 90°

beam angle with ground= 51

beam angle with wall =39

because total angle=angle with ground + angle with wall

angle with wall=total angle-angle with ground

angle with wall= 90-51=39
