The coordinates of point A on a coordinate grid are (−2, −3). Point A is reflected across the y-axis to obtain point B and acros
amid [387]

Answer:

B) B(2,-3) and C(-2,3)

Step-by-step explanation:

The given point A, has coordinates (-2,-3).

When point A(-2,-3) is reflected over the y-axis to obtain point B, then the coordinates of B is obtained by negating the x-coordinate of A.

Therefore B will have coordinates (2,-3).

 When point A(-2,-3) is reflected over the x-axis to obtain point C, then the coordinates of C is obtained by negating the y-coordinate of A.

Hence the coordinates of C are (-2,3)

20 pointss please help I appreciate it <333
ivanzaharov [21]

Answer:

DE = 7.07 RS = 11.04 not congruent

Step-by-step explanation:

Formula:

d=\sqrt{(x2-x1)^2 + (y2-y1)^2}

D (5,0) E (0,-5)

DE

d=\sqrt{(0-5)^2 + ( -5 - 0)^2}

d=\sqrt{(-5)^2 + (-5)^2}

d=\sqrt{25+25}

d=\sqrt{50}

d= 7.07

R (-5,-5) S (6,-6)

RS

d=\sqrt{(6-(-5))^2 + (-6 - (-5))^2 }

d=\sqrt{11^2 + (-1)^2}

d=\sqrt{121 + 1}

d=\sqrt{122}

d= 11.04
