Answer:

reflect across x axis: (x,-y)

reflect across y axis: (-x,y)

reflect across y=x: (y,x)

reflect across y= -x: (-y,-x)

90 cc rotation: (-y,x)

180 rotation: (-x,-y)

270 cc rotation: (y,-x)

Step-by-step explanation:

reflect across x axis: (x,-y) - x coor stays same and only y coor becomes negative

reflect across y axis: (-x,y) - x coor becomes negative and y coor stays the same

reflect across y=x: (y,x) - both coordinate switch places, no signs are changed

reflect across y= -x: (-y,-x) - both coordinates switch places and the signs are switched to the opposite sign of the original number

90 cc rotation: (-y,x) - opposite of the original y coor and both coordinates switch place (same as 270 clockwise)

180 rotation: (-x,-y) - both coordinates stay in there original place but with the opposite values of the original value

270 cc rotation: (y,-x) - both coordinates switch places and the x values is the opposite of the original value (same as 90 clockwise)

*to find the third columns answer all you have to do is plug in the given x and y values into the coordinate rule

You roll 2 number cubes. What is the probability of rolling double twos?<br> EZ points!
Misha Larkins [42]

Answer:

Step-by-step explanation:

There are 6 ways we can roll doubles out of a possible 36 rolls (6 x 6), for a probability of 6/36, or 1/6, on any roll of two fair dice. So you have a 16.7% probability of rolling doubles with 2 fair six-sided dice.

Combining the like-terms, the result of the addition of polynomials f(x) and g(x) is given by:

f(x) + g(x) = 21x^3 + \frac{5}{4}x^{\frac{1}{2}} + 19x^{-\frac{1}{4}} + 8x^{-4}

<h3>How do we add polynomials?</h3>

We add polynomials combining the like-terms, that is, adding terms with the same exponent.

In this problem, the polynomials are:

  • f(x) = 3x^{\frac{1}{2}} + 7x^{-\frac{1}{4}} + 8x^{-4}
  • g(x) = -\frac{7}{4}x^{\frac{1}{2}} + 12x^{-\frac{1}{4}} - 21x^3

Combining the like terms, the addition is given by:

f(x) + g(x) = \left(3 - \frac{7}{4}\right)x^{\frac{1}{2}} + (7 + 12)x^{-\frac{1}{4}} + 8x^{-4} + 21x^3

f(x) + g(x) = 21x^3 + \frac{5}{4}x^{\frac{1}{2}} + 19x^{-\frac{1}{4}} + 8x^{-4}
