bro i no cap got the same q?
Step-by-step explanation:
Answer:
y = 40/3
Step-by-step explanation:
For greater clarity please write 3y-8/12 =y/5 as:
3y-8 y
-------- = ------
12 5
Cross-multiplying, we get:
15y - 40 = 12y
Combining the y terms yields 3y = 40, so that y = 40/3
...6 and 10 are roots, so x – 6 and x – 10 are factors.
y = a(x – 6)(x – 10).....plug in the point (8, 2) and solve for a:
2 = a(8 – 6)(8 – 10)
2 = –4a
a = –1/2
...y = (–1/2)(x – 6)(x – 10)
...y = (–1/2)(x² – 16x + 60)
...y = (–x²/2) + 8x – 30 <<<------Answer, or:
...y = (–1/2)(x – 8)² + 2 <<<------Answer
