(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
That answer was (B)................
Answer: She would save $175.08 during each of the next 2 weeks.
Step-by-step explanation:
Jasmine's plane ticket cost $466.88. She has already saved 25% of the cost of the ticket. This means that the amount that she already saved is
25/100 × 466.88 = $116.72
The amount remaining would be
466.88 - 116.72 = $350.16
During the next 2 weeks, she will save 1/2 of the remaining cost of the ticket. This means that the amount that she would save during each of the next 2 weeks is
1/2 × 350.16 = $175.08
Answer:
-23x = 7
Step-by-step explanation:
-3x - y =0
×5. ×5 ×5
-15x -5y = 0
-8x +5y = 7
-15x -5y -0
-23x = 7
