Answer:
(-7,4)
Step-by-step explanation:
goal: (y-k)^2=4p(x-h)
y^2-8y=4x+12 Rearranged and added 4x and 12 on both sides
y^2-8y+(-8/2)^2=4x+12+(-8/2)^2 complete square time (add same thing on both sides)
y^2-8y+(-4)^2=4x+12+(-4)^2 (simplify inside the squares)
(y-4)^2=4x+12+16 (now write the left hand side as a square)
(y-4)^2=4x+28
(y-4)^2=4(x+7) factored...
vertex is (-7,4)
I say step 4 is incorrect.
Answer:
what is the question? please ask a question.
C. 3x-2 1. you split the second terms into two terrms.
2. factor out common terms in the first two terms, then in the last two terms
3. factor out the common term 3x-2
cancel out x-5
and your left with 3x-2
Step-by-step explanation:
Let the no. be x
Therefore , the no. is 390
