Answer: Dont come after me if im wrong buut, what i think you mean is reflecting a point over the y axis would mean the y stays the same, but x changes to be negative or positive depending on its quadrant.

Step-by-step explanation:

point: (8,5) reflected over axis= (-8,5)

          .(-8,5)       |             (8,5)

                          |    

                          |  

                          |  

   ____________________(x)

                          |

                          |

                          |(y)

x + y = 6. 2x - y = 3. The system of equations. . . a.has no solution. b.has one solution. c.is coincident
balu736 [363]

Answer:

<u>The answer is the option B</u>

The system has one solution

Step-by-step explanation:

we have

x+y=6 ------> equation A

2x-y=3 ------> equation B

Adds equation A and equation B

x+y=6\\2x-y=3\\-------\\2x+x=6+3\\3x=9\\x=3

Find the value of y

Substitute the value of x in equation A or equation B

3+y=6

y=3

therefore

The system has one solution

What is 2/5 of a book to 1/2 of an hour as a unit rate?
hjlf

Answer: 4/5 book per hour

Step-by-step explanation:                                                                        in this question, we are to rewrite (2/5)/(1/2) as unit rate.

To write this as a unit rate, what we need to do  is to divide 2/5 by 1/2.

That means 2/5 divided by 1/2

Removing the division and replacing with multiplication will give 2/5 * 2/1 = 4/5 books/hour

Please someone help me solve this question
miv72 [106K]

Answer:

  D.  right 4, down 8

Step-by-step explanation:

The usual transformations applied to functions are ...

  f(x) ⇒ f(x -h) . . . . translation right h units

  f(x) ⇒ f(x) +k . . . . translation up k units

  f(x) ⇒ k·f(x) . . . . . vertical scaling by a factor of k; reflection over x-axis when k < 0

  f(x) ⇒ f(x/k) . . . . . horizontal scaling by a factor of k; reflection over y-axis when k < 0

In the above, "scaling" will be expansion when |k| > 1, compression when |k| < 1.

__

Your transformation is ...

  x^2 ⇒ (x -4)^2 -8

  f(x) ⇒ f(x -4) -8

This is translation with h=4 and k=-8. That is, it is translation right 4 units and down 8 units.

_____

<em>Additional comment</em>

Like much of math, it is all about matching patterns.
