(4,3) is the intersection (where the graphs meet
Answer:
B
Step-by-step explanation:
Population density= population/land
(1.2*10^6)/(1.1*10^4)
EE N would be 10 to the power of N
in other words the population would be
1.2*EE 6
and land would be
1.1*EE 4
Which would make the keystroke
1.2EE6/1.1EE4
which is equal to B
Answer:
a = 
Step-by-step explanation:
When working with fractions, I would mostly like to make the denominators the same first.
a - 
= 
Make all the denominators 6.
a - = 
Isolate a.
a = +
= 
Find a.
a = 
×
a =
Answer:
Step-by-step explanation:
Given:
(y/y - 4) - (4/y + 4) = 32/y^2 - 16
Note y^2 - 16 = (y - 4 ) × (y + 4)
Multiplying the equation; both sides by y^2 - 16,
y (y + 4) - (4(y - 4)) = 32
y^2 + 4y - 4y + 16 = 32
y^2 = 32 - 16
Squaring both sides,
y = sqrt(16)
= 4
