the birth rate in a certain country in 1994 was 14,6 birthd per thousand population. in 2004 the birth rate was 14.32 per thousa
amm1812

Answer:

y(x)=-0.028x+14.6

Step-by-step explanation:

Birth Rate in 1994 =  14.6 births per thousand population.

Birth Rate in 2004 =  14.32 births per thousand population.

A linear equation is of the form: y=mx+c

Where:

  • x=years after 1994
  • y=the birth rate
  • m=Yearly Birth Rate

First, we determine the birth rate per year

m=\dfrac{14.32-14.6}{10-0}\\=\dfrac{-0.28}{10}\\m=-0.028

Therefore, a linear equation that relates y in terms of x is of the form:

y(x)=-0.028x+c

When x=0, y=14.6

14.6=-0.028(0)+c

c=14.6

Therefore, the linear equation that relates y in terms of x is:

y(x)=-0.028x+14.6

The recipe calls for I cup of water to be mixed with 6 cups of cake mix. How much water should be mixed with 21 cups of cake mix
enot [183]
1/x=6/21

What you need to do is set it up as a proportion.  1 cup to 6 cups cake mix, x cups to 21 cups cake mix.  

21/6 is 3.5

So 3.5 cups of water to 21 cups of cake mix (:

Hope this makes sense!
