When graphed, the three lines y.** 2. y. 2x-1, and y--2 intersect in such a way that they form a triangle What are the coordinates of the three vertices of this triangle?

OA (2.0), (0, 2), and (-1,-3)
OB. (0, 2), (2.0), and (1,-1)
OC (1, 1), (2.0), and (-1,-3)
.D. (1,1),(0, 2), and (-1,-3)
Of (2.0), (1, -1), and (-1,-3)

(1,1); (2,0) and (-1,-3)

Step-by-step explanation:

Given

---- (1)

--- (2)

---- (3)

Required

The vertices of the triangle

To do this, we simply equate the equations.

Equate (1) and (2)

Collect like terms

Divide by -3

Substitute in (1), to get the y-coordinates

So, the coordinate is: (1,1)

Equate (1) and (3)

Collect like terms

Divide by -2

Substitute in (1) to get the y coordinate

So, the coordinate is (2,0)

Equate (2) and (3)

Collect like terms

Substitute in (2) to get the y coordinates

So, the coordinate is (-1,-3)

the clues that signal the reader should change tone are the punctuation marks, the grammatical signs. for example, the quotation marks at the beginning of something someone else said literally or the exclamation marks.

the tone of the first line of dialogue until "gettysburg" is a kind tone, a tone of advise. the narrator is trying to the other person in doing something he or she obviously is finding hard to do by giving a piece of advise and bringing up a memory of a successful similar case.

the clue that the reader understand how to read the word "bang" is the exclamation mark. it gives the word a surprise tone, a strong accent.

the best tone for reading the word "bang" is an exciting tone, a surprise one, even a loud one.

the words that should be read with a formal tone are the ones that give factual information. the sentence: mister lincoln couldn't think of anything to say at the gettysburg" gives information about an event and it needs to be read formally, also, when the narrator wants to transmit calmness, a formal and slow tone is needed, because people also transmit messages with the vibrations of our voices and tones.

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)
