That would be A. because 75*74 because he had 75 students to pick the first time and 74 to pick the second student. So in short the answer is A.
While your statements are missing, there are a few things we can tell about the graph from the equation:
The vertex is at (3, -1). We know this because the equation is in vertex form,
y=a(x-h)²+k, where (h, k) is the vertex.
The graph opens upward and has a minimum. This is because there is no negative before the squared term.
The y-intercept of the graph is at (0, 8). We know this because if we substitute 0 for x, we have
y=(0-3)²-1 = (-3)²-1 = 9-1 = 8
The answer is
<span>x+1</span>, <span>x+2</span>, <span>x+3</span>, <span>x+4</span> and <span>x+5</span>.
The sum of these six integers is 393 so we can write:
<span>x+x+1+x+2+x+3+x+4+x+5=393</span>
<span>6x+1+2+3+4+5=393</span>
<span>6x+15=393</span>
<span>6x+15−15=393−15</span>
<span>6x+0=378</span>
<span><span><span>6x</span>6</span>=<span>3786</span></span>
<span>x=63</span>
Because the first integer is 63 then the third would be <span>x+2</span> or <span>63+2=<span>65</span></span>
