What is the vertex of the graph of y = x2 + 4x?<br> (–2, –12)<br> (–2, –8)<br> (–2, –6)<br> (–2, –4)

SCORPION-xisa [38]

Answer: The vertex of the parabola (quadratic function) is (-2,-4)

Fourth option: (-2,-4)

Solution:

y=x^2+4x

y=ax^2+bx+c; a=1, b=4, c=0

Vertex: V=(h,k)

h=-b/(2a)

h=-4/(2(1))

h=-4/2

h=-2

y=x^2+4x

k=y=h^2+4h

k=(-2)^2+4(-2)

k=4-8

k=-4

Vertex: V=(h,k)

Vertex: V=( -2, -4)

I need help with question number one please help?

1) Area of trapezoid =1/2(base 1 +base 2)* height

$A= \frac{23 \frac{1}{3}+4 \frac{2}{3} }{2} *(12 \frac{3}{4} ) = \frac{27 \frac{3}{3} }{2} *( \frac{51}{4} ) = \frac{28}{2} * \frac{51}{4} = \frac{7*51}{2} = \frac{357}{2} =178 \frac{1}{2} x^{2}$

Pls help, write an equation then solve for x

tamaranim1 [39]

Answer:

x= $\frac{1}{6}n+\frac{\sqrt{2} }{4}$

Step-by-step explanation:

mutiply both sides of the equation by 6

12x-2n=3 $\sqrt{2$

move the bariable to the right hand side and change its sign

12x=3 $\sqrt{2$ +2n

divide both sides

x= $\frac{\sqrt{2} }{4}$ +1/6n

use commutative propert to reorder the terms

x= 1/6n + $\frac{\sqrt{2} }{4}$

and thats it, i hope this helps ya!
