Answer:
y₁=x₁+0.04x₂
y₂=x₂+0.06x₁
Step-by-step explanation:
In the first year, number of people who live:
In the city= x₁
In the suburb=x₂
New Population in the next year
In the city= y₁
In the suburb=y₂
If each year 6% of the city population moves to the suburb,
New Suburb Population=Previous Population+Immigrants
y₂=x₂+0.06x₁
If each year 4% of the suburb population moves to the city,
New City Population=Previous Population+Immigrants
y₁=x₁+0.04x₂
y₁=x₁+0.04x₂
y₂=x₂+0.06x₁
Answer:x = -12

Answer:
2261,9 cm³
Step-by-step explanation:
First, you need to find the area of the base:

A=36
cm²
Now let's multiply it for the height:
36π cm² × 20 cm = 720π cm³
= 2261,9 cm³
Answer:
z = 17.5
Step-by-step explanation:
segment RX is an angle bisector and divides the opposite side into segments that are proportional to the other 2 sides, that is
=
, substitute values
=
( cross- multiply )
6z = 105 ( divide both sides by 6 )
z = 17.5
