Answer:
The vertex is the point 
Step-by-step explanation:
we know that
The general form of an absolute value equation is
The variable a tells us how far the graph stretches vertically, and whether the graph opens up or down. The variables h, and k, tell us how far the graph shifts horizontally and vertically
The vertex is the point (h,k)
we have
Rewrite the expression (3x+1)
substitute
therefore
The vertex is the point

Answer:
y = 
Step-by-step explanation:
given y varies as the square of x then the equation relating them is
y = kx² ← k is the constant of variation
to find k use the given condition y = 25 when x = 3
k = 
= 
⇒ y = x²
when x = 2
y = × 4 =
Can smart people answer.??????? Corinna is taking a test in which short-answer questions are worth 10 points each and essay questions are worth 15 points each. She estimates that it takes 3 min to answer each short- answer question and 6 min to answer each essay question. The total time allowed is 60 min, and no more than 16 questions can be answered. Assuming that all her answers are correct, how many questions of each type should Corinna answer in order to get the best score?
The number 7 should be removed from his list to make the list accurate.
So your number is z and you want 9 less z-9
