Answer:
x ≥ 4
Step-by-step explanation:
Given
- 4(8 - 3x) ≥ 6x - 8 ← distribute parenthesis on left side
- 32 + 12x ≥ 6x - 8 ( subtract 6x from both sides )
- 32 + 6x ≥ - 8 ( add 32 to both sides )
6x ≥ 24 ( divide both sides by 6 )
x ≥ 4
The a value in the expression is 5x^2
Answer:
cos 2 x=1-sin^2 x
Step-by-step explanation:
x=-135°
cos 2x=cos (-270)=cos (-270+360)=cos 90=0
or cos 2x=1-2sin ²x=1-2(sin (-135))²
=1-2(-sin 135)²
=1-2(sin 135)²
=1-2(sin (180-45))²
=1-2(sin²45)
=1-2 (\frac{1}{\sqrt{2}})²
=1-1
=0
<h2>
Hello!</h2>
The answer is:
The function is greater or equal to 0 at the points (-3,6), (-2,0), (0,6) and (4,0).
<h2>
Why?</h2>
To find where the function is greater or equal to 0, we need to look (using the graph) where the function is above the x-axis
So, we can see that the function is above the x-axis from the point (-3,6) to the point (4,0), for these points, the function is greater or equal to 0.
Hence, the function is greater or equal to 0 at the points (-3,6), (-2,0), (0,6) and (4,0), or the function is greater or equal to 0, from -3 to 4 (x-axis values or input).
We have that:
Have a nice day!
