Answer:
It would be y = 2x+4
Step-by-step explanation:
This is because Isabella has started with 4 baked pies and is gaining additional pies with in amounts of 2 pies.
With this, 4 would be by itself and 2 would be attached to the variable x for the unknown amount of additional pies.
Lastly, you would have this all equaling y, as y is the total amount of pies.
You could have ANY rule you want. Just substitute for and for but MAKE SURE THAT ONCE YOU SIMPLIFY IT, IT IS TRUE. Lets start making some equations!
How about:
If we substitute into it, we find it works.
How about:
By the way, if you substitute y and x into the equation above, you will find they also work.
Thank you, and I hope this helped.

It will take 16.66years long for the money to double
The formula for calculating the compound amount is expressed as:
A = P(1+r)^t
- A is the amount after t years = 2(900) = $1800
- P is the amount invested = $900
- r is the rate in decimal = 4.25% = 0.0425
Substitute into the formula to have:
1800 = 900(1+0.0425)^t
2 =(1+0.0425)^t
2 = 1.0425^t
ln2 = tln1.0425
t = ln2/ln1.0425
t = 0.6931/0.0416
t = 16.66years
This shows that it will take 16.66years long for the money to double

Answer:
All that apply is 18 20 22 24
Step-by-step explanation:
Given:
Manuel has 18 yards of fabric to make table runners.
It takes 3/4 yard to make each runner.
The question is
How many yards runners can Manuel make i.e. 3/4 yard runner with 18 yards
To get all that apply, we will have to divided the yards of fabrics by yards used
= 18 ÷ ¾
= 18 X (4/3)
= 18 x 1.3333
= 23.9
≅ 24
