O(x, y) - (-x, y). (X. y) (x + 1, y + 1)
O(x, y) - (x, -y), (x, y) (X + 2, Y + 2)

Answer:

  (b)  (x, y) ⇒ (-x, y); (x, y) ⇒ (x + 1, y + 1)

Step-by-step explanation:

A graph shows the image is consistent with reflection over the y-axis

  (x, y) ⇒ (-x, y)

and translation right 1, up 1

  (x, y) ⇒ (x +1, y +1)

These transformations are listed in the second choice.

__

In the attachment, the original image is blue, the reflected image is purple, and the final translated image is red.

Maurinko [17]

Answer:

≈ 82 feet

Step-by-step explanation:

Since the triangle is right use Pythagoras' identity to calculate distance (d)

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides.

Here the hypotenuse is the distance (d) between the 2 poles, hence

d² = 80² + 45² = 6400 + 2025 = 8425 ( take the square root of both sides )

d = \sqrt{8425} ≈ 82 feet ( to the nearest foot )

karen is 3 yrs younger than floyd. floyd is 2 years older than maria. marias age is the smallest two-digit number. how old are t
Alinara [238K]

Answer:

Maria is 10, Floyd is 8, and Karen is 5.

Step-by-step explanation:

Having said that Maria's age was the smallest two-digit number, that's ten. (10). If Floyd is 2 years younger then 10-2=8. Karen is 3 years younger, so she would be 8-3=5.

Find the value of x and y
Naddik [55]
Just a guess, but the angle inside the triangle that's not x or y is the remaining angle after subtracting the 30 degrees shown.  That makes the non labeled angle inside the triangle 150 degrees.  since all triangles are 180 degrees, this means x and y add up to 30.  They look roughly the same, so i'd guess they're both 15 degrees.

Earnings = 5 + 7.50x  You want to earn 50.00

50 = 5 + 7.50x             Set up equation  

45 = 7.50x                    Subtract 5

45/7.50 = (7.50/7.50) x Divide by 7.5

x = 6

You need to work 6 hours.
