Step-by-step explanation:

- 3m - 6 = 6 - 7m

+7m         +7m

4m -6 = 6

+6         +6

4m=12

Answer:

the vertex is:

(2, -1)

Step-by-step explanation:

First solve the equation for the variable y

x^2-16y-4x-12=0

Add 16y on both sides of the equation

16y=x^2-16y+16y-4x-12

16y=x^2-4x-12

Notice that now the equation has the general form of a parabola

ax^2 +bx +c

In this case

a=1\\b=-4\\c=-12

Add (\frac{b}{2}) ^ 2 and subtract (\frac{b}{2}) ^ 2 on the right side of the equation

(\frac{b}{2}) ^ 2=(\frac{-4}{2}) ^ 2

(\frac{b}{2}) ^ 2=(-2) ^ 2

(\frac{b}{2}) ^ 2=4

16y=(x^2-4x+4)-4-12

Factor the expression that is inside the parentheses

16y=(x-2)^2-16

Divide both sides of the equality between 16

\frac{16}{16}y=\frac{1}{16}(x-2)^2-\frac{16}{16}

y=\frac{1}{16}(x-2)^2-1

For an equation of the form

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

the vertex is: (h, k)

In this case

h=2\\k =-1

the vertex is:

(2, -1)

Which statement is true about the product 3(7square root of 4 + 2square root of 9? It is rational and equal to 60. It is rationa
kogti [31]

It is rational, since actually


\sqrt{4}=2,\quad\sqrt{9}=3


so, the expression simply beco3(7\sqrt{4} + 2\sqrt{9})=3(7\cdot2+2\cdot 3)=3(14+6)=3\cdot 20 = 60
