Need help with this math question

Answer:

The vertex is: $(6, 8)$

Step-by-step explanation:

First solve the equation for the variable y

$x^2-4y-12x+68=0$

Add 4y on both sides of the equation

$4y=x^2-4y+4y-12x+68$

$4y=x^2-12x+68$

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

$ax^2 +bx +c$

In this case

$a=1\\b=-12\\c=68$

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

$(\frac{b}{2}) ^ 2=(\frac{-12}{2}) ^ 2\\\\(\frac{b}{2}) ^ 2=(-6) ^ 2\\\\(\frac{b}{2}) ^ 2=36$

$4y=(x^2-12x+36)-36+68$

Factor the expression that is inside the parentheses

$4y=(x-6)^2+32$

Divide both sides of the equality between 4

$\frac{4}{4}y=\frac{1}{4}(x-6)^2+\frac{32}{4}$

$y=\frac{1}{4}(x-6)^2+8$

For an equation of the form

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

the vertex is: (h, k)

In this case

$h=6\\k =8$

the vertex is: $(6, 8)$

A student solved the given equation and justified every step except one. What is the missing reason? A) Associative property of

Anna007 [38]

Given:

The statements and reasons to solve an equation.

To find:

The missing reason.

Solution:

If a, b and c are three real number, then

Associative property of addition : $(a+b)+c=a+(b+c)$

Commutative property of addition : $a+b=b+a$

Multiplicative property of equality : $a=b\Leftrightarrow ca=cb$

Distributive property of multiplication over addition : $a(b+c)=ab+ac$

In the given step, $(x+-3)+3$ is written as $x+(-3+3)$ .

It means, only parenthesis are changed, which is possible by Associative property of addition.

So, the missing reason is Associative property of addition.

Therefore, the correct option is A.

In your own words, explain what is the difference between SIMPLE and COMPOUND probability.

denpristay [2]

Answer:

Step-by-step explanation:

Simple events are events where one experiment happens at a time and it will have a single outcome such as tossing a coin. Compound events are events where there is more than one possible outcome such as roll a five using a 6-sided die

there are two identical glasses. one glass is 5/6 full. the other is 3/4 full. water is poured from one glass to the other so th

goldenfox [79]

Answer:

1 7/12

Step-by-step explanation:

because the water was poured to the other glass so it means that we are adding

= 5/6 + 3/4

={(2×5) + (3×3)}/12

that 12 is due to LCM of 6 and 4

={ 10 + 9 }/12

= 19/12

= 1 7/12

those are my thoughts

Options 2 -2 1 -1 PLEASEE HELP ME

Vilka [71]

Answer:

slope = - 1

Step-by-step explanation:

Calculate the slope m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (2, 8) and (x₂, y₂ ) = (6, 4)

m = $\frac{4-8}{6-2}$ = $\frac{-4}{4}$ = - 1
