Answer:

15. f(x) +g(x) = 7x +2

16. f(x) -g(x) = -3x +8

17. h(x) · g(x) = 35x -21

Step-by-step explanation:

Substitute the function definition for each function expression and simplify.

15. f(x) + g(x) = (2x +5) +(5x -3)

f(x) +g(x) = 7x +2

16. f(x) - g(x) = (2x +5) -(5x -3)

f(x) -g(x) = -3x +8

17. h(x) · g(x) = (7) · (5x -3)

h(x) · g(x) = 35x -21

The rabbit population in a certain area is 500% of last year's population. There are 700 rabbits this year. How many were the

Ksenya-84 [330]

For this case we have the following data:

700 rabbits that represent 500% of the population of last year. So, to obtain the rabbit population of last year, we developed a rule of three:

700 -----------> 500%

x ---------------> 100%

Where x represents the rabbit population of last year.

Clearing x we have:

$x = \frac{ 100 * 700}{500}$

$x = 140$ rabbits

In this way, last year there was a population of 140 rabbits.

140 rabbits
