Weegy: The excluded value for x is -1/4 or negative one-fourth. Excluded values are values that will make the denominator of a fraction equal to 0. [ You can't divide by 0, so it's very important to find these excluded values when you're solving a rational expression. ]

Find the vertex of the parabola whose equation is y = x2 + 2x + 9.
Question
Updated 2/6/2015 1:04:22 AM
The vertex of the parabola whose equation is y = x^2 + 2x + 9 is (-1,8).
x = -2/(2*1) = -2/2 = -1
when x = -1
y = (-1)^2 + 2*(-1) + 9
y = 1 - 2 + 9
y = 8

2(4x + 5) > 7x + 20

8x + 10 > 7x + 20

8x + 10 - 7x > 20

x + 10 > 20

x > 20 - 10

x > 10

-4(x - 7) + (x + 14)
= - 4x + 28 + x + 14
=(- 4x + x) + (28 + 14)
= - 3x +42
