Answer:

<h2>B. reflection across the origin.</h2>

Step-by-step explanation:

In this transformation, "reflection across the origin" wasn't applied, because the triangle is in the opposite side. Reflection across the origin is like having a mirror in the origin.

On the other hand, by rotation we get the transformation as it's shown, because the triangle would be in that exact spot. Similarly, if we reflect across the line y = -x, the triangle would be like that, because when we reflect across such line, all coordinates are changed by its opposite, for example C(1,3), changes to C'(-1,-3), which actually happens.

Therefore, the right answer is B.

A website received 2500 registered members in July. And the number of registered members in August decreased to 2245. What was t

quester [9]

Number of registrations a website received during July = 2500

Number of registrations a website received during August = 2245

Number by which the registrations decreased :

$=\tt 2500 - 2245$

$=\tt 255$

Thus, the registrations decreased by 255.

Let x be the perrcentage of decrease.

Which means :

$=\tt 255 = \frac{x}{100} \: of \: 2500$

$= \tt255 = \frac{x \times 2500}{100}$

$=\tt 255 = \frac{2500x}{100}$

$= \tt255 \times 100 = 2500x$

$= \tt25500 = 2500x$

$=\tt \frac{25000}{2500} = x$

$\color{plum} =\tt \bold{10.2\%}$

▪︎Thus, the percentage of decrease in the number of registered members = 10.2%

-(y-7)=14 solve the following equation

enyata [817]

First, distribute the negative sign and get -y + 7 = 14

then subtract 7 from both sides and get -y = 7

Divide both sides by -1 and get y = -7

Hope this helps :)

Two concentric circles with different radii share how many common tangent lines?

Dominik [7]

The answer is a.0

Concentric means these circles would have the same center, thus, the smaller circle must be inside the bigger circle. Any tangent line to the smaller circle wont be a tangent line to the bigger circle, since that tangent line would intersect at the bigger circle at 2 points. Any tangent line to the big circle will not touch the small circle... so the answer would be 0.
