Answer:

3,750 cars.

Step-by-step explanation:

We are given that the equation:

y=9000-2.4x

Models the relationsip between <em>y</em>, the number of unfilled seats in the stadium, and <em>x</em>, the number of cars in the parking lot.

We want to determine the number of cars in the parking lot when there are no unfilled seats in the stadium.

When there are no unfilled seats in the stadium, <em>y</em> = 0. Thus:

0=9000-2.4x

Solve for <em>x</em>. Subtract 9000 from both sides:

-2.4x=-9000

Divide both sides by -2.4:

x=3750

So, there will be 3,750 cars in the parking lot when there are no unfilled seats in the stadium.

Define polynomial with some examples.
Veseljchak [2.6K]

Answer:

A Polynomial can be expressed in terms that only have positive integer exponents and the operations of addition, subtraction, and multiplication. In other words, it must be possible to write the expression without division.

Step-by-step explanation:

<em>EXAMPLES :</em>

  • <em> x2 + 2x +5 Since all of the variables have integer exponents that are positive this is a polynomial.</em>
  • <em>5x +1 Since all of the variables have integer exponents that are positive this is a polynomial.</em>
  • <em>(x7 + 2x4 - 5) * 3x Since all of the variables have integer exponents that are positive this is a polynomial.</em>
  • <em>5x-2 +1 Not a polynomial because a term has a negative exponent</em>
  • <em>3x½ +2 Not a polynomial because a term has a fraction exponent</em>
  • <em>(5x +1) ÷ (3x) Not a polynomial because of the division</em>
  • <em>(6x2 +3x) ÷ (3x) Is actually a polynomial because it's possible to simplify this to 3x + 1 --which of course satisfies the requirements of a polynomial. (Remember the definition states that the expression 'can' be expressed using addition,subtraction, multiplication. So, if it's possible to simplify an expression into a form that uses only those operations and whose exponents are all positive integers...then you do indeed have a polynomial equation) </em>

You and your sister have been saving and decide to buy a Playstation 5 together. You need $500 to
AveGali [126]

According to the information given, we have that:

a) The system of equations is given by: x + y = 850, 0.5x + 0.75y = 500.

b) You has saved $550 and your sister has saved $300.

<h3>What is a system of equations?</h3>

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

In this problem, the variables are:

  • Variable x: The amount you have saved up.
  • Variable y: The amount your sister has saved up.

Item a:

Together you have $850 saved up, hence:

x + y = 850.

You contribute 50% of your savings and your sister contributes 75% of hers toward the $500 cost, hence:

0.5x + 0.75y = 500.

Item b:

From the first equation, we have that:

x = 850 - y

Replacing on the second:

0.5(850 - y) + 0.75y = 500

0.25y = 75

y = 75/0.25

y = 300

x = 850 - y = 550.

You has saved $550 and your sister has saved $300.
