scZoUnD [109]3 years ago

We keep brackets

(4n^2 + 3n - 5 ) -  (2n^2 + 3n + 6)

We change signs and we group

4n^2 - 2n^2 + 3n - 3n - 5-6

We simplify

2m^2 - 11

Answer: = 2.n^2  - 11

which must be true of a quadratic function whose vertex is the same as its y-intercept? the axis of symmetry for the function is
Sholpan [36]

If <u>quadratic function </u>y=ax^2+bx+c has <u>vertex </u>that is the same as its <u>y-intercept</u>, then

x_v=-\dfrac{b}{2a}=0,\\ \\b=0

and its equation is y=ax^2+c.

The graph of this quadratic function is translated graph of the function y=ax^2 up or down (depends on c).

This means  that there could be

  • two x-intercepts;
  • one x-intercept;
  • no x-intercepts.

The axis of symmetry of the graph of the function y=ax^2 is x=0 (y-axis).

Answer: correct choice is A

Choose the correct answer. A balance sheet has assets listed on the left, and liabilities and (blank) on the right.
Nonamiya [84]

Answer:

A balance sheet has assets listed on the left, and liabilities and <u>OWNERS EQUITY</u> on the right.

Step-by-step explanation:

A balanced sheet shows a company's assets, liabilities and owners equity at a specific point in time. it shows what a company owns and owes and the amount invested by shareholders.

Assets are the valuable property or money they have that is assets provide income in futures. examples  cash, investments, supplies, land, buildings, equipment, etc.

Liabilities are the debt taken by a person like loans, rents to be paid , mortgages, etc.

Owners equity is the book value of the company that is owner's equity is equal to the  asset amounts minus the liability amounts.

Owner's Equity = Assets - Liabilities.

Rearranging, We get

<u>Assets = Liabilities + Owner's Equity </u>

Account receivables, cash and equipment all are a parts of assets.

Thus,  A balance sheet has assets listed on the left, and liabilities and <u>OWNERS EQUITY</u> on the right.

Hi!

<h3>Divide by -10 on both sides. </h3>

-10x/-10 < -100/-10

<h3>The inequality sign flips because we are dividing by a negative number. </h3>

<u>x > 10</u>

<h2>The answer is A x > 10</h2>

Hope this helps! :)
