Multiply out the "a times the squared coefficient" part on the left-hand side (remember, in this one a = 1 so that does nothing), and convert the right-hand side to squared form. (This is where you use that sign you kept track of earlier, putting that sign in the middle of the squared expression.)
y-4+(9)=(x+3)^2
Simplify - combine like terms.
y+5=(x+3)^2
Move the constant term from the right back to the left.
y=(x+3)^2 - 5
Write in vertex form y=(a(x-h)^2) + k. In other words, if the squared term is x+h write it as x-(-h). If the k term is negative, write it as + (-k).
y=(x-(-3))^2 + (-5)
Now the values for h and k are clear.I hope that this is the answer that you were looking for and it has helped you.
Question 33 is A because a open circle means not included whereas a closed circle means included.
The difference of four times a number and 5 is 39 can be expressed algebraically as:
4x - 5 = 39
Now, we can solve for x.
Add 5 to both sides:
4x - 5 + 5 = 39 + 5
4x = 44
Divide both sides by 4 to solve for x:
4x/4 = 44/4
x = 11

Answer:
x=1
Step-by-step explanation:
7/3 x + 1/3x = 1 + 5/3 x
Combine like terms
8/3 x = 1 +5/3 x
Subtract 5/3 x from each side
8/3x -5/3x = 1 + 5/3x -5/3x
3/3x = 1
x =1
