UkoKoshka [18]

Answer:

68

Step-by-step explanation:

Let x=adult tickets and y=child tickets

1) 15x+11y=1889

2) x+y=147

multiply equation 1 by -1/11 on both sides to get:

-(15/11)x-y=-171.73

add new equation with equation 2 to get

-4/11x=-24.73

Isolate x to get:

x=67.99999

Round up to get 68 adult tickets

What is the vertex form of y=2x^2-8x+1
bezimeni [28]

Answer:

2(x-2)^2-7

Step-by-step explanation:

y=2x^2-8x+1

When comparing to standard form of a parabola: ax^2+bx+c

  • a=2
  • b=-8
  • c=1

Vertex form of a parabola is: a(x-h)^2+k, which is what we are trying to convert this quadratic equation into.

To do so, we can start by finding "h" in the original vertex form of a parabola. This can be found by using: \frac{-b}{2a}.

Substitute in -8 for b and 2 for a.

\frac{-(-8)}{2(2)}

Simplify this fraction.

\frac{8}{4} \rightarrow2

\boxed{h=2}

The "h" value is 2. Now we can find the "k" value by substituting in 2 for x into the given quadratic equation.

y=2(2)^2-8(2)+1

Simplify.

y=-7

\boxed{k=-7}

We have the values of h and k for the original vertex form, so now we can plug these into the original vertex form. We already know a from the beginning (it is 2).

a(x-h)^2+k\\ \\ 2(x-2)^2-7

Dmitry_Shevchenko [17]
Sierah907 Your primary job’s gross income is $3,468.73/month. Deductions are FICA (7.65%), federal tax withholding (11.5%), and state tax withholding (7.8%). How much are your fixed expenses if they are 36% of your realized income?


$1,388.65


$814.92


$912.21


$1,068.57





<span>To get your realized income you: add your deductions which equals to a total of 26.95%. 

Then you subtract that amount  from your gross income. 
(3468.72 - 26.95% = 2533.91) 

 After that you need to find what 36% of your realized income equals to: 

and it equals to, 912.20. 

Therefore, your answer is C.




Answer 2: </span>

our deductions are 7.65% , 11.5% and 7.8% . Total 26.95% .

So deduct that from your Gross . $3468.73 - 26.95% leaves you with $ 2533.91.
That's your Realized Income . $2533.91 .

So you need to find 36% of that . It's $912.20.

<span> And that is your answer . Your fixed expenses are $ 912.20 . </span>
