Answer:
Step-by-step explanation:
Step one:
we are told that the relationship between the number of species and the island area is given as
-----------------1
based on any given value for either area or number of species, we can find the other.
say we want to find the land area for a given amount of specie
Step two:
we first make area A subject of the formula.
let us isolate 
Divide both sides by 103.2 we have
Now, exponentiate both sides using the base e.
----------------2
for a given value of "S" we can find the area A based on the above expression.
Answer:
c none of the above
Step-by-step explanation:
not a because x is never in the original expression
not b because you are subtracting something that should be added
2.5 hopefully this helpsss
Answer:
135
Step-by-step explanation:
5 times 35 equals 135
Answer
x=-2 and y=-3
Step-by-step explanation:
Step: Solvey=5x+7for y:
Step: Substitute5x+7 for y in 3x+y=−9:
3x+y=−9
3x+5x+7=−9
8x+7=−9(Simplify both sides of the equation)
8x+7+−7=−9+−7(Add -7 to both sides)
8x=−16
8x/8=−16/8
(Divide both sides by 8)
x=−2
Step: Substitute−2 for x in y=5x+7:
y=5x+7
y=(5)(−2)+7
y=−3(Simplify both sides of the equation)
