<span>f(x) = 3x - 7. you replace Y with f(x) because f(x) is the inverse of y</span>
Answer:
18
Step-by-step explanation:
x+6x = 21
7x = 21
x = 21/7
x = 3
substitute x value in 6x to find second number,
= 6x
= 6*3
Answer:
1 solution
Step-by-step explanation:
The solution is the intersection point, which is at (3, -2)
We will use the formula for finding the surface area of a rectangular prism.
Formula =
SA <span>= </span><span>2 </span><span>(</span><span>w</span><span>l</span><span>+</span><span>h</span><span>l</span><span>+</span><span>h</span><span>w</span><span>)</span>SA = 2 (8·14 + 4·14 + 4·8)
SA = 2 (112 + 56 + 32)
SA = 2 (200)
SA = 400

Step-by-step explanation:
a).
It is given that rate at which the population increases is directly proportional to size of the population. Thus we have,
It is given in the question that the population increases by 2% in one day. Now we know that the time in days is a continuous variable, so we have
2% of P =
b).
It is given that the population is harvested by 4 % in one day
(Since 4% of the P is harvested.)
c).
It is given that 1000 fish are being harvested or removed in one day.
d).
The threshold is given by
or
