It is called a fact Family
For the first one it is x= (y+3)/4
Answer: x=-1 y=1
Step-by-step explanation:
solve y in 3+2x-y=0
y=3+2x
sub y=3+2x into -3 -7y=10x
-14x- 24= 10x
solve x in -14x-24=10x
x= -1
sub x= -1 into y =3+2x
y=1
so therefore x= -1 and y=1
Answer:
14.2 hectares
Step-by-step explanation:
Fund Mexico, monarch butterflies occupied 1.13 hectares one recent winter, and 4.01 hectares the following winter (one year later)
The formula of Geometric growth
(Pt/ Po)^1/t
Where Pt = Size after t years = 4.01 hectares
Po = Initial size = 1.13
t = times = 1
=( 4.01/1.13 )^1/1
= 3.5486725664
Hence, Geometric growth rate = 3.5486725664.
It's size in hectares after another 1 year = Current size in hectares × Geometric growth rate
= 4.01 ×3.5486725664
= 14.230176991 hectares
≈ 14.2
