Sin(a + b) = sin(a)cos(b) + sin(b)cos(a)
sin(x + pi) = sin(x)cos(pi) + cos(x)sin(pi)

sin(pi) = 0cos(pi) = -1

sin(x + pi) = sin(x)(-1) + cos(x)(0)
sin(x + pi) = -sin(x) + 0

Dante's parents gave him a fish tank containing 20 goldfish. Each month, Dante gives away 2 goldfish from his fish tank to
mr_godi [17]

The inequality that can be used to find m, the number of months after receiving his fish tank, when Dante will have less than 10 goldfish in his fish tank is 20 - 2m < 10

Since Dante has 20 goldfish and gives out 2 goldfish every month,

After one month, he has 20 - 2 = 20 - 1(2) gold fish left.

After 2 months, he has 20 - 2 - 2 = 20 - 4 = 20 - 2(2) goldfish left.

After 3 months, he has 20 - 2 - 2 - 2 = 20 - 6 = 20 - 3(2) goldfish left.

<h3>Number of goldfish after m months</h3>

So, after m months, he has 20 - 2m goldfish left.

<h3>The inequality to find m</h3>

For the number of goldfish to be less than 10, we have the inequality

20 - 2m < 10

So, the inequality that can be used to find m, the number of months after receiving his fish tank, when Dante will have less than 10 goldfish in his fish tank is 20 - 2m < 10
