Answer: 12
Step-by-step explanation: I just guessed
X²=12x-5
minus 12x both sides
x²-12x=-5
take 1/2 of the linear confident and square it
-12/2=-6, (-6)²=36
add that to both sides
x²-12x+36=-5+36
factor perfect square
(x-6)²=31
sqrt both sides, remember to take positive and negative roots
x-6=+/-√31
x=6+/-√31
the solutions are 6+√31 and 6-√31
Answer: M= slope
M= -1/5
Step-by-step explanation:
M= the change in y over the change in x so you would do 1-4 over 13-(-2) which gives you -3 over 15 which is simplified to give you the answer which is -1/5.
Answer:
(x - 3)(x + 3)
Step-by-step explanation:
a² - b² = (a - b)(a + b)
x² - 9 = (x - 3)(x + 3)
