Answer:

D is correct

Step-by-step explanation:

2x/(x-2) - (x+5)/(x+3)

2x(x+3)/(x-2)(x+3) - (x+5)(x-2)/(x+3)(x-2)

2x^2+6x/(x-2)(x+3)-(x^2+3x-10)(x+3)(x-2)

(x^2+3x+10)/(x+3)(x-2)

What is the answer for this math?​
Westkost [7]

Answer:

x=-4.992 and x=-0.434

Step-by-step explanation:

we have    

\frac{\sqrt{3x+15}}{5}=2^{x}

we can divide the equation above into two equations

so

y=\frac{\sqrt{3x+15}}{5} ----> equation A

y=2^{x} ----> equation B

Solve by graphing

The solutions of the system are the x-coordinates of the intersection points both graphs

using a graphing tool

The solutions are x=-4.992 and x=-0.434

see the attached figure

In line 53, the author of Passage 2 uses quotation
notsponge [240]

(E) "cast doubt on the aptness of a description"

Writers will occasionally include a term or phrase in quotation marks to question its veracity. The author of paragraph 2 denigrates the learning theorists by putting the word "experts" in quotation marks because of their "shocking" estimate of canine intelligence.

The answer is not (A). One may contend that the author's use of quote marks conveys surprise or even irritation. (B) is the wrong answer. The term "experts" being surrounded by quotation marks is not a show of "respect," but rather of suspicion.

The answer is not (C). There is no need to doubt the plain usage of the word "experts" in this context, even when the author may have reservations about the theories of the experts. D is likewise a poor choice.

Here's another question with an answer similar to this about quotation marks: brainly.com/question/1434552
