Answer:
You can not write an equation then because it would just be a vertical line, ex: x=4 or x=-4. I hope this helps!
Step-by-step explanation:
5x + 4y = 10
- 5x - 5x
4y = -5x + 10
4 4
y = -1¹/₄x + 2¹/₂
The answer is D.
Answer:
4320
Step-by-step explanation:
there are 36 inches in a yard so 120 times 36
4 - 4y - y² = 0
-y² - 4y + 4 = 0
y = -(-4) ± √((-4)² - 4(4)(-1))
2(-1)
y = 4 ± √(16 + 16)
-2
y = 4 ± √(32)
-2
y = 4 ± 4√(2)
-2
y = 4 + 4√(2) or y = 4 - 4√(2)
-2 -2
y = -2 - 2√(2) or y = -2 + 2√(2)
The answer is C.
