Tan x + 1 = 0
tan x = -1
x = -π/4 + nπ ( n ∈ Z )
Answer:

Step-by-step explanation:

Answer:
C because the line doesn't touch the x axis
Step-by-step explanation:
1] ⬇
p - (6 - 2(q))➡0
p + 2q - 6➡0
q = 3 because 6÷2 = 0
p = 6 because 6 ÷ 1 = 6
Slope ➡ 0.5
-----------------------------------------------------------------
2] ⬇
p - (1 + q)➡0
p - q- 1➡0
Q = -1 because 1 ÷ -1 ='-1
P = 1 because 1 ÷ 1 = 1
Slope ➡ 1
The answer is B; $ 59.00. All you have to do is multiply the price times 4 and then subtract that from 100. Then do it again and 59 should be your answer.
