Try to use long division! To calculate a fraction as a decimal, you can act like the slash is a division symbol.
So, to calculate 1/6 as a decimal, divide 1 by 6 on a sheet of paper (or a calculator) and you’ll find out what it is.
1. Move the negative sign to the left.
- ![\frac{19}{8}](https://tex.z-dn.net/?f=%5Cfrac%7B19%7D%7B8%7D)
*-50
2. Use this rule: ![\frac{a}{b}](https://tex.z-dn.net/?f=%5Cfrac%7Ba%7D%7Bb%7D)
![*](https://tex.z-dn.net/?f=%2A)
=![\frac{ac}{bd}](https://tex.z-dn.net/?f=%5Cfrac%7Bac%7D%7Bbd%7D)
-![\frac{19x*-50}{8}](https://tex.z-dn.net/?f=%5Cfrac%7B19x%2A-50%7D%7B8%7D)
3. Simplify - ![\frac{-950x}{8}](https://tex.z-dn.net/?f=%5Cfrac%7B-950x%7D%7B8%7D)
4. Move the negative sign to the left.
-(-950x/8)
5. Simplify 950x/8 to 475x/4
6. Remove parentheses.
If the growth rate is a constant, we can model it using a linear equation:
y = b + ax
where b = initial value, a = growth rate.
In this case, x = m = number of months.
Let's find the equation for the growth of each species.
Species A:
Initial height = b = 25 cm
Growth rate = a = 3 cm per month
So its height can be modeled by H(m) = 25 + 3m
Species B:
Initial height = b = 10 cm
Growth rate = a = 8 cm per month
So its height can be modeled by H(m) = 10 + 8m
Thus the answer is A: H(m) = 25 + 3m and B: H(m) = 10 + 8m.
Answer:
X Y
1 25
3 17
4 13
6 5
Step-by-step explanation:
All we need to do is substitute the x values into the equation and we will find the y values!
