Alright so, let’s break this down.

To find the first coordinate you need to solve the first equation

To do that you can do
6+9=15
So that mean 3x has to be equal to 15
You divide 15 by 3

The answer to that is the solution to the first equation, or the first coordinate.

For the second one, you know x has to be negative because the solution is negative

2x is going to have to equal -20
-20/2 gets you the solution

Remember that it will be negative
You now have both of the coordinates

You take coordinate A and technically add coordinate B to it
You do that because B is negative and A is positive
Then you have the answer to c

the original price for a set of golf clubs is $500 at the beginning of the seasons the price was marked up by 20% at the end of
Blizzard [7]

Answer: The final price is less than the original

Step-by-step explanation:

    Let us break this down a bit.

The original price is $500

-> At the beginning, the price was marked up by 20%

-> At the end, the price at the beginning of the season is marked down by 20%

    We are solving for: "How does the final price compare with the original price of $500​"

        First, we will find the price at the beginning.

-> Please note a percent divided by 100 becomes a decimal

20% / 100 = 0.2

$500 * 0.2 = $100

$500 + $100 = $600

     Now, we will find the price at the end.

$600 * 0.2 = $120

$600 - $120 = <u>$480</u>

     The final price is less than the original price of $500.

The kite area can be calculated using the formula
a = 1/2 × d₁ × d₂
with d₁ as first diagonal and d₂ as second diagonal

From the question, we know that
d₁ = 9.5 + 9.5
d₁ = 19 in

d₂ = 7 + 12
d₂ = 19 in

Calculate the area by plugging in the numbers into the formula
a = 1/2 × d₁ × d₂
a = 1/2 × 19 × 19
a = 1/2 × 361
a = 180.5

The area of the kite is 180.5 in²
The answer is fourth answer
