if we zero out f(x), namely make y = 0, we can get the roots or x-intercepts for this quadratic equation
now, the equation is in x-terms, meaning is a vertically opening parabola, so the axis of symmetry will be x = something, a vertical line.
well, we have two x-intercepts, one at -4 and another at 2, and the vertex is right half-way between those guys
-4------------(-1)------------2
so the vertex is at x=-1, namely the axis of symmetry is x = -1.
Answer: A)
x = # of students in math class
2x+7=40
B)
2x+7=40
-7

x = 76 students
Noed of them because it would have to end in two zeros

Answer:
12 inches
Step-by-step explanation:
Translation is a rigid transformation. The translated object is congruent to the original, so has all the same dimensions.
The perimeter of ∆A'B'C' is 12 inches.
Without rounding, I make it six. You could do it this way
54527/5^6 comes to a little over 3. That should be close enough. I'm going to check this by doing the divisions. I could let the computer do it, but I'd like to see if there's a pattern. There isn't and the correct answer is
6 <<<< divisions.
