Answer:
Step-by-step explanation:
General equation of circle with center at (0, 0) : x² + y² = r²
x² + y² = 56.25
x² + y² = 7.5²
Radius = 7.5 units
Center (0 , 0)
Hi !
625 - (625 ÷ 25) - 25 = 575
Answer:
Given any initial point (x, y), a reflection across the y-axis means the y-coordinate remains the same but the sign of the x-coordinate changes. Therefore, the coordinate expression that gives the coordinates of the point after a reflection across the y-axis is (-x, y).
