sin (x) = -1
arcsin (-1) = x
x = -90
and multiples of 360
x =-90, 270,....
x =-90 + 360n where n is an integer
or in radians
-pi/2 + 2*pi *n where n is an integer
Answer:
x = ± 2
Step-by-step explanation:
Given
2x² + 11 = 131 ( subtract 11 from both sides )
2x² = 120 ( divide both sides by 2 )
x² = 60 ( take the square root of both sides )
x = ± = ± = ± 2
Answer:
<h3>The answer is x = 5</h3>
Step-by-step explanation:
The statement
3x less than two times the sum of 2X and one is written as
2( 2x + 1) - 3x
the sum of 2 and 5 is written as
2 + 5
Equate the two statements
We have
2( 2x + 1) - 3x = 2+5
Expand
4x + 2 - 3x = 7
Simplify
4x - 3x = 7 - 2
We have the final answer as
<h3>x = 5</h3>
