C' is the image after C(-4,-2) after a reflection across the y-axis. What are the coordinates of C'?

(4,-2)

Step-by-step explanation:

r y-axis: (x,y) ⇒ (-x,y)

(-4,-2) ⇒ (4,-2)

The coordinates of C is = (-4,2)

Step-by-step explanation:

y-axis

(x, y) →→→→→→→→→→→ (-x, y)

(-4,-2) →→→→→→→→→→→ (-4,2)

step-by-step explanation:

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
