Answer:
x = 0, π/3, π, 5π/3
Step-by-step explanation:
sec(x)sin(x) - 2sin(x) = 0
factor out sin(x)
sin(x)[sec(x) - 2] = 0
then solve by splitting into two parts:
sin(x) = 0 and sec(x) - 2 = 0
x = 0, π and x = π/3, 5π/3 then plug in to original equation to check
Answer:
x = 0
Step-by-step explanation:
2x + 161 = x + 46 + 115
Subtract x
x + 161 = 161
Subtract 161
x = 0
Answer: 
Step-by-step explanation:

Distribute 1/4


add 5/2




Subtract 2x





Multiply by the negative reciprocal of -7/4 which is basically inverting the fraction -4/7


<h3>hello!</h3>
First of all, subtract 5 from both sides:-
13-5<z+5-5
13-5<z
8<z
Since 8 is less than z, z is greater than 8:-

Hence, all the numbers greater than 8 will make this inequality true.

Hope everything is clear; if you need any explanation/clarification, kindly let me know, and I will comment and/or edit my answer :)
Answer:
x =
or 14.78
Step-by-step explanation:
The lines are parallel, therefore, k(18) acts same as g(x)
That means that:
k(18) = g(x)
- 14 =
+ 24
- 14 - 24 =
- 38 =
38(7) = 18x
266 = 18x
266 / 18 = x
133 / 9 = x
x =
or 14.78
