To give a simple answer
if you consider the equation to be that of a line.
then if the variables cancel out, then the two lines will have the same slope.
two lines with the same slope fall under two categories. Parallel lines, and lines on top of each other
parallel lines have no solutions since the lines never cross each other
lines on top of each other have infinitely many solutions since they "cross" everywhere on the line
We have that
point B (-3,-2)
point C (0,2)
the distance between B and C is
d=√(y2-y1)²+(x2-x1)²--------> d= √(2+2)²+(0+3)²-------> d=√25
d=5 units
the answer is
<span>the length of segment BC is 5 units
using a graph tool

It’s rational, for a number to be rational you have to be able to write it as a fraction and you can write 0.515115111511115111115... as a fraction.
Answer:
2744 Rhinos will be left after 10 years
Step-by-step explanation:
This question has to do with exponential decay rate. We solve this using the formula:
P(t) = Po(1 - r)^t
Where P(t) = Amount left after t years
Po = Initial amount
r = Decay rate = 3.7% = 0.037
t = time in years = 10 years
P(t) = 4000(1 - 0.037)¹⁰
P(t) = 4000 × 0.963¹⁰
P(t) = 4000 × 0.6859032667003232
P(t) = 2743.6130668
Approximately = 2744 Rhinos will be left after 10 years
