Identify the vertex of y = x^2 + 4x + 5

docker41 [41]

Answer:

D. (-2,1)

Step-by-step explanation:

we have

$y=x^2+4x+5$

This is the equation of a vertical parabola open upward The vertex represent a maximum

Convert the quadratic equation in vertex form

$y=a(x-h)^2+k$

where

(h,k) is the vertex

Complete the square

$y=(x^2+4x+2^2)+5-2^2$

$y=(x^2+4x+4)+5-4$

$y=(x^2+4x+4)+1$

Rewrite as perfect squares

$y=(x+2)^2+1$

The vertex is the point (-2,1)

Ax = bx + 1. How is the value of x related to the difference of a and b?

Zielflug [23.3K]

Answer:

x = 1/(a-b)

Step-by-step explanation:

The given equation is ax = bx + 1

Collecting like terms:

ax - bx = 1

Factorizing x out of the equation:

x(a - b) = 1

Dividing both sides by (a - b):

$\frac{x(a - b)}{(a - b)} = \frac{1}{a - b} \\x = \frac{1}{a - b}$

Therefore, x is related to the difference of a and be by the equation

x = 1/(a-b) where a - b is the difference of a and b
