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

8x + 10 > 7x + 20

8x + 10 - 7x > 20

x + 10 > 20

x > 20 - 10

x > 10

8x + 10 > 7x + 20

8x + 10 - 7x > 20

x + 10 > 20

x > 20 - 10

x > 10

-7z/4z+1 **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. ] (More)

Find the vertex of the parabola whose equation is y = x2 + 2x + 9.

Question

Updated 2/6/2015 1:04:22 AM

1 Answer/Comment

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

x = -2/(2*1) = -2/2 = -1

when x = -1

y = (-1)^2 + 2*(-1) + 9

y = 1 - 2 + 9

y = 8

-4(x - 7) + (x + 14).

Question

Updated 5/4/2018 3:47:07 AM

1 Answer/Comment

-4(x - 7) + (x + 14)

= - 4x + 28 + x + 14

=(- 4x + x) + (28 + 14)

= - 3x +42

= - 4x + 28 + x + 14

=(- 4x + x) + (28 + 14)

= - 3x +42
