Answer:
(- 1, 8 )
Step-by-step explanation:
Under a reflection in the line y = x
a point (x, y ) → (y, x ) , thus
(8, - 1 ) → (- 1, 8 )
-8 and 8 in my opinion i’m not a 100% sure

Answer:
C. -3, -2, 2, and 3
Step-by-step explanation:
x⁴ - 13x² + 36 = 0
(x²-4) (x²-9) = (x+2)(x-2)(x+3)(x-3) =0
x = 2 or x = -2 or x = 3 and or x = -3
I’m not sure but i think the smaller number is 4 and the larger is 7. i got this because 4×2=8 and 8-1=7. i tried it with 3 and it didn’t work and neither did 5.
small- 4
large- 7
not sure though
