The <em>quadratic</em> equation has the following results: (p, q) = (8, 15), minimum point: (h, k) = (1, 4), range of values: - 4 < x < - 3

<h3>How to analyze quadratic equations</h3>

In this question we have a <em>quadratic</em> equation of the form y = x² + p · x + q , whose <em>missing</em> coefficients can be found by solving on the following system of <em>linear</em> equations:

- 5 · p + q = - 25

- 3 · p + q = - 9

(p, q) = (8, 15)

The vertex represents the <em>minimum</em> point, which is found by changing the form of the equation from <em>standard</em> form into <em>vertex</em> form:

y = x² + 8 · x + 15

y + 1 = x² + 8 · x + 16

y + 1 = (x + 4)²

(h, k) = (1, 4)

And lastly we must solve for x in the following inequality:

x² + 8 · x + 15 < x + 3

x² + 7 · x + 12 < 0

(x + 3) · (x + 4) < 0

- 4 < x < - 3

Describe the steps you would take to solve for the variable x in the following
adoni [48]

Answer:

x =  19

Step-by-step explanation:

1. add 31 on both sides (you wanna get the "x" by itself)

ex: 2x - 31 = 7

          +31   +31

2. the 31s cancel each other out so now you add 31 + 7

2x       =  7

           +31

___________

             38

3. divide 2 on both sides so the 2s cancel each other out and only the x is left

ex: 2x / 2 = x         38 ( the 38 stands alone)

4. now divide 38/2 and you have your answer

X= 19
