GEOMETRY HELP please you will get 10 points and a friend
Flura [38]
The answer is: the Y axis. :I
You reflect it, then you shift the shape 1 unit to the right. For example, Point U is at coordinates, -2, 2. Reflected across the Y axis, it's 2, 2. Then to get to the point that U' is at, you shift your reflected U to the right one unit. That gets you to coordinates 3, 2. Same thing goes for the other Points. Cx Hope this helped!!

Rocio leaves point A traveling due east at 40 miles per hour. At the same moment, Li leaves point A traveling due west at 50 mil
Afina-wow [57]
Their speed of separation will be equal to the sum of their speeds because they are in opposite directions.
Speed of separation = 40 + 50 = 90 miles per hour

Time = distance / speed
Time = 405 / 90
Time = 4.5 hours

A circle has its center at (−1, 2) and a radius of 3 units. Find the equation of the circle using the Pythagorean Theorem. PLEAS
notka56 [123]
Pythagorean Theorem is for triangles not circles. 

The equation of a circle is (x - h)² + (y - k)² = radius² where (h, k) is the center.

Plug in your given information and simplify.

(x - (- 1))² + (y - 2)² = (3)²

(x + 1)² + (y - 2)² = 9 is your equation.
