Answer:

10) C

11) C

Substitute all values of x in y = 3x + 2 to solve

y = 3(0) + 2 = 2

y = 3(2) + 2 = 8

y = 3(3) + 2 ≠ 5

y = 3(5) + 2 = 17

What is x? I will give brainliest if you explain your answer.

horsena [70]

Answer:

x = {0, π/2, 3π/2, 2π}

Step-by-step explanation:

cotx cos x - cot x = 0
cotx( cosx - 1) = 0

1. cotx = 0

x = π/2 + πn
In the interval [0, 2π] we have π/2 and 3π/2

2. cosx = 1

x = 0 + 2πn
In the given interval we have 0 and 2π

So the solution set is:

x = {0, π/2, 3π/2, 2π}
