A1 = 5
d = a2-a1 = 2-5 = -3

a(n) = a + (n - 1)d \\ a(n) = 5 + (n -1) - 3 \\ a(n) = 5 - 3(n - 1)

Write the expression as the sine, cosine, or tangent of an angle.
erma4kov [3.2K]

Answer:

tan56°

Step-by-step explanation:

The Addition identity for tangent ratio is

tan(x + y) = \frac{tanx+tany}{1-tanxtany} , thus

\frac{tan24+tan32}{1-tan24tan32} = tan(24 + 32)° = tan56°

1 . Solve 4x + 5 > 5x − 2 for x.
Kobotan [32]

I will do number 1 only. You can then use my solution steps to do the rest.

Solve 4x + 5 > 5x − 2 for x.

4x + 5 > 5x − 2

4x - 5x > - 2 - 5

-x > -7

Dividing both sides by a negative number reverses the inequality sign. In other words, the sign > becomes < in the reply.

-x/-1 < -7/-1

x < 7

Answer: x < 7

The answer here means that whatever the value of x is for question 1, it must be less than 7.

You finish.
