The answers are
focus: (−2,3)
directrix: y=7
vertex: (−2,5)
The vertex is at the point (−2,5), the focus is at the point (−2,3), and the directrix is the line at y=7.
Hope this helps
Infinite solutions, both end up being the same line
Answer:
C
Step-by-step explanation:
to factor x² - x - 2
consider the factors of the constant term which sum to give the coefficient of the x-term.
the factors are - 2 and + 1 since - 2 × 1 = - 2 and - 2 + 1 = - 1
x² - x - 2 = (x - 2)(x + 1), hence (x + 1) is a factor
$29,000 ×4%= 29,000 ×4/100 = 116,000/100 = 1,160
Soo
29,000 - 1,160 = 27,840
