Answer: This is a quadratic equation in x and can be solved using the quadratic formula: x = (-b +_ (b^2 - 4 ac)^1/2) / (2 * a)

or (-7 +- (49 - (4 * 2 * 6))^1/2) / (2 * 2) where a=2, b=7, and c=6

and x = (-7 +- (49 - 48)^1/2) / 4 = (-7 +- 1) / 4

giving x = -8/4 and -6/4 or -2 and =3/2

Solve the following system of equations. What is one x-value of a solution?

gulaghasi [49]

Answer:

There is some mistake in the question, because the solutions are x = -1.445 and x = -34.555

Step-by-step explanation:

Given the functions:

f(x) = x² + 4x + 10

g(x) = -32x - 40

we want to find the points at which f(x) = g(x).

x² + 4x + 10 = -32x - 40

x² + 4x + 10 + 32x + 40 = 0

x² + 36x + 50 = 0

Using quadratic formula:

$x = \frac{-b \pm \sqrt{b^2-4(a)(c)}}{2(a)}$

$x = \frac{-36 \pm \sqrt{36^2-4(1)(50)}}{2(1)}$

$x = \frac{-36 \pm 33.11}{2}$

$x_1 = \frac{-36 + 33.11}{2}$

$x_1 = -1.445$

$x_2 = \frac{-36 - 33.11}{2}$

$x_2 = -34.555$
