⇒ 
Since , 
⇒ 
Now , General Solution is given by :
⇒ 
Therefore , Solution to equation
for all real values of x is
.
45 x 5 = 225 so 225 students altogether on 5 buses
It shows you the exact distance from each number and it's easier to find out how far apart they are.
2y+14=28
-14=-14

2y=14
14/2=y
Y=7
Y = x^2 + 2x - 1 = x^2 + 2x + 1 - 1 - 1 = (x + 1)^2 - 2
The vertex of a parabola given by y = a(x - h)^2 + k is (h, k).
Therefore, the vertex of y = (x + 1)^2 - 2 is (-1, -2)
