X² + y² - 10 x - 12 y + 36 = 0
( x² - 10 x + 25 ) + ( y² - 12 y + 36 ) - 25 - 36 + 36 = 0
( x - 5 )² + ( y - 6 )² = 25
( x - 5 )² + ( y - 6 )² = 5²
Answer:
The center: ( 5, 6 ), the radius: r = 5
First, we have to calculate how much time it takes Laine to read one page.
240 / 200 = 6 / 5 (six fifths of a minute)
Then, we need to find out how much time it takes her to read 25 pages.
25 * 6 / 5 = 150 / 5 = 30 minutes
A: It will take Laine 30 minutes to read 25 pages at the same rate.
The answer would be 3x^2 I think.
Answer:
(x+2)(x+8)=0
Step-by-step explanation:
the first term x² can only be factored by (x) times(x), and the last term 16 has factors of 16&1, 4&4 or 8&2. only 8 &2 have a sum of 10x (the middle term) so
(x+2)(x+8)=0
Answer:
this is the answer for the first exercice (hope this help)
