D. since if you plug in the Pythagorean therom it comes out true and the Pythagorean therom only works on right triangles. also isosceles have 2 side lengths the same.
Answer:
c. (-4, 0)
Step-by-step explanation:
F(X) = -3X - 4
Y = -3X-4
SWAP X AND Y: x = -3y -4
y = -1/3x - 4/3
f⁻¹(x) = -1/3x - 4/3
point (-4,0): x = -4 y = f⁻¹(-4) = (-1/3)*(-4) - 4/3 = 4/3 - 4/3 = 0
1 5/8
Trust me :)
