In a survey in 2010, the population of two plant species were found to be growing exponentially. their growth is given by these equations: species a, p=2000e ^0.05t and species b, p=5000e^0.02t , where t = 0 in the year 2010.

4. after how many years will the population of species a be equal to the population of species b in the forest?

y < -3

step-by-step explanation:

-3y - 2 > 7

-3y -2 + 2 > 7+2

-3y > 9

-3y/-3 < 9/-3   (change the inequality sign when multiplying or dividing by a negative number)

y < -3

costs the what? what is the cost of the pants?

step-by-step explanation:

if it is $10, then the price is 14.

take 40% of the cost, and then add the cost.

40% of 10 = 4

4+10 = 14.

the domain of a function is the set of input values, x , for which a function is defined. the domain is shown in the left oval in the picture below. the function provides an output value, f(x) , for each member of the domain.

-60.75

step-by-step explanation:

just add the numbers then put the negative sign on it
