A rational number can be expressed as a fraction with an integer numerator and denominator. The square root of 2 is irrational, and adding 4.2 doesn't change this, since there are no integers that, when divided, form this sum.
Answer:

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

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

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:

C because the x's repeat with the 3 and 3. If the x's repeat it is not a function.
Hope that helps.
Answer:
Corresponding angles are equal. They're a F shape and it could be upside down.
Answer:
330=40x+50
Step-by-step explanation:
then you would -50 from both sides
280=40x
then you would divide both sides by 40 to isolate x
7=x
so that means it would take 7 weeks
