The discount amount would be $1470.00

the new cost of the car would be $19530.00

For given question,

A car dealer gave a 7% discount to the first 50 people through the door.

the car you are interested in cost $21,000.00

We need to find the discount amount and the new price of the car.

A car dealer gave a 7% discount.

this means, to find the discount amount, we need to find the 7 percent of $21,000.00

⇒ discount amount = 7 percent of $21,000.00

⇒ discount amount = (7 / 100) × 21,000.00

⇒ discount amount = $1470.00

So, the new price of the car would be,

the new price of the car = original price - discount amount

⇒ the new price of the car = $21,000.00 - $1470.00

⇒ the new price of the car = $19530.00

Therefore, the discount amount would be $1470.00

the new cost of the car would be $19530.00

Four friends hosted a Graduation party: Genesis spent $21 for drinks, Mya spent $25 for food, Alina spent $16 for invitations, a
Naya [18.7K]

Answer:

Alina owes $4 to Mya and Mylana owes $1 to Mya and $1 to Genesis.

Step-by-step explanation:

As they want to share the party expenses equally, first you have to add all the expenses and divide them by 4 people to know the amount that each person has to pay:

$21+$25+$16+$18= $80/4= $20

As everyone has to pay $20 for the party expenses, we can see that Genesis spent $1 more and Mya $5 more, so they have to get the money back from the other 2 people.

Alina owes: $20-$16= $4. She owes $4 to Mya as she will pay the entire amount she owes to one person and Mya has to get $5 back.

Mylana owes: $20-$18= $2. She would have to pay $1 to Mya to complete the $5 she had to get back and $1 to Genesis.

If f(x) = –4x^2 – 6x – 1 and g(x) = –x^2 – 5x + 3, find (f – g)(x)
SpyIntel [72]

Answer:

B

Step-by-step explanation:

Note (f - g)(x) = f(x) - g(x)

f(x) - g(x)

= - 4x² - 6x - 1 - (- x² - 5x + 3) ← distribute parenthesis by - 1

= - 4x² - 6x - 1 + x² + 5x - 3 ← collect like terms

= - 3x² - x - 4 → B

Trying to factor as a Difference of Squares:

2.1 Factoring: 9x{}^{2}-1

Theory : A difference of two perfect squares, A{}^{2} - B{}^{2} can be factored into (A+B) • (A-B)

Proof : (A+B) • (A-B) =

A{}^{2} - AB + BA - B2 =

A{}^{2}- AB + AB - B2 =

A{}^{2} - B2

Note : AB = BA is the commutative property of multiplication.

Note : - AB + AB equals zero and is therefore eliminated from the expression.

Check : 9 is the square of 3

Check : 1 is the square of 1

Check : x{}^{2} is the square of x1

Factorization is : (3x + 1) • (3x - 1)

Final result :

(3x + 1) • (3x - 1)
