Answer:
See answer below
Step-by-step explanation:
x² - 10x + 30 = 0
x² - 10x = -30
x² - 10x + 25 = -30 +25 1/2 of the x term and square that number and add to
both side.
x² -10x + 25 = -5
(x - 5)(x - 5) = -5
=
If you are in Algebra II , then the answer is not a real answer it will be
(x - 5)² = ±5i
Answer:
670.9
Step-by-step explanation:
because 670.9 is bigger and 670.008 has more 0's and 0's aren't greater
First thing to do is to switch the x and the y and then solve for the new y. Easier said than done! Here's our equation with the switch:
. We need to get that y out from inside that exponent. This is an exponential equation, and the inverse of an exponential equation is a log equation. Let's do some simplifying here first:
. The 2 is now the base of our log (x-6) so now we have
, which is the last choice above.
