(x-4)² + (x-2)² = x²
(x² - 8x + 16 ) + (x² - 4x + 4) = x
2x² -12x + 20 = x
2x²-12x + 20 - x = 0
2x² - 13x + 20 = 0
(2x-5) (x-4) = 0
2x-5 = 0
2x = 5
x = ⁵/₂
x-4 = 0
x = 4
so x₁ = ⁵/₂ , and x₂ = 4
Answer:
B. y = -5x -2
Step-by-step explanation:
Fill in the given values in the form ...
y = (slope)x + (y-intercept)
y = -5x +(-2)
y = -5x -2 . . . . simplify; matches choice B
