Answer:
y = 13
Step-by-step explanation:
Step 1: Distribute
3/2y - 3/2 = y + 5
Step 2: Subtract <em>y</em> on both sides
1/2y - 3/2 = 5
Step 3: add 3/2 on both sides
1/2y = 13/2
Step 4: Divide both sides by 1/2
y = 13

Answer:
Completing the square is always confusing, but if you keep in mind it's just a way to write (A + B )^2 so that the problem is in some easier form it makes a bit better sense. A perfect square has some helpful properties.. anyway..
Step-by-step explanation:
Given: - 12x +23 = 0 ( not a perfect square , tough to work with )
take 1/2 of the second term coefficient 12/2 = 6 and square it
- 12x + (
+23 =
-12x +
+23 =
now there is a perfect square :)
(x - 6)^2 =36-23
(x - 6)^2 = 13
take the square root of both side now
x -6 =
x = +6
sooo what is supposed to happen in these problems is that square root of 13 is supposed to work out to something that is easy to find the root of ... maybe in your answers you left out the square roots? so maybe A is right :/
