Answer:
Dot 1. y = 3, x = 1
Dot 2. y = 6, x = 2
Dot 3. y = 12, x = 4
Dot 4. y = 18, x = 6
Step-by-step explanation:
Distance(m) = y
Time(s) = x
Therefore whatever is traveling at that speed is getting faster (A Perpetual Energy Producing Bullet) since at first it goes a = 3 Distance(m) and then duplicates its distance and Time traveled which makes sence. Then it does the same thing again! (∑²ᵇ⁽¹⁾) This is the mathematical equation that changes it. It basically means it takes a sum of the last number than multiplies it by itself to the power of (2ᵇ) and then to the power of 1 to finish off the equation. (∑²ᵇ⁽¹⁾) = ( (u x 2) x2) + c) = Infinite power looping then taking breaks in between to take a variable that was 2 last of itself and add that to the sum of the entire equation!
c = (u x 2)!
Hope this helps!

Answer:
Ok tell me which mathematic game
Since they decided to be extremely ridiculous and deleted my answer for "not showing enough work", here I am again:
Since it says that Kiwi is 13 less than TWICE Granny's age, I divided 77 (Granny's age) by 2, which gave me 38.5
I then subtracted 13, since it says that she is thirteen less than that number, which gave me 25.5
I had originally said "20 or 20 and a half years old" because depending on your format of testing/worksheet, you may not have the option of putting halves.
Answer:
<em>x = 4 / 3, y = 7 / 3</em>
Step-by-step explanation:
We are given the following system of equations;
{ 7x - y = 7, ⇒ Let us multiply the first equation by 2,
x + 2y = 6 }
2 * ( 7x - y = 7 ) ⇒ 14x - 2y = 14 ⇒ Now add the two equations
+ x + 2y = 6 + x + 2y = 6
14x + x = 14 + 6 ⇒ Simplify
15x = 20,
<em>x = 4 / 3</em> ⇒ Now substitute this value of x into the first equation to solve for the value of y,
7 * ( 4 / 3 ) - y = 7 ⇒ Simplify,
28 / 3 - y = 7,
y = 7 / 3
<em>Solution; x = 4 / 3, y = 7 / 3</em>
"on sale for 12% off" means that whatever the price is (y) we multiply it by 0.88 since 1-0.12 = 0.88
Price before discount = original price = y
Price after discount = 0.88y
Put another way, we took 88% of the original price to get the discount price.
------------------------------------
Now tack on the sales tax. We do this by multiplying the discount price by 1.03 (1 + 0.03 = 1.03)
So we have:
final cost = 1.03*(discount price)
final cost = 1.03*(0.88y)
final cost = 0.9064y
telling us that the final cost is 90.64% of the original price (y). With the tax added, the discount is not 12% but actually 100% - 90.64% = 9.36%
