Find the vertex and length of the latus rectum for the parabola. y=1/6(x-8)^2+6
Answer:
m∠QPR = 25°
Step-by-step explanation:
m∠QPS = 40° and is the degree of m∠RPS and m∠QPR added together.
(9x + 16) + (8x + 7) = 40
17x + 23 = 40
- 23 - 23
17x = 17
x = 1
Then plug in what you get for x to get m∠QPR
9(1) + 16 = 9 + 16 = 25
Answer: is Graph A! Hope this help:)
$200 x 12 = 2,400 (number of pencils they bought in 2006)
3/4 x 2,400 = 1,800 (number of pencils they used)
2,400 - 1,800 = 600 (number of pencils remaining)
1,800 - 600 = 1,200 (number of pencils needed)
They had to buy 1,200 more pencils in 2007.
