The other x-intercept is located at (-8,0). This is because the vertex is ALWAYS the midpoint between the two x-intercepts. The x coordinate of the vertex is 2. The distance between the vertex and the known x-intercept is 10 units. So go 10 units to the left now, which lands at x = -8
Well current we know that one house takes 5/6 of an Acura. Therefore 7 houses will take up:
5/6 * 7 = 5.83333333333331 Acuras
Ans: 7 houses will require 5.83 Acuras
Assume the second number is x, then the other two are x - 2, x + 2
So x-2 + x + x + 2 = 51
-> 3x = 51
-> x = 17
