Answer:
It's odd.
Explanation:
A function is odd when <span><span>f<span>(−x)</span></span>=−<span>f<span>(x)</span></span></span>
<span><span>f<span>(−x)</span></span>=6<span><span>(−x)</span>3</span>−2<span>(−x)</span></span>
<span>=−6<span>x3</span>+2x</span>
<span>=−<span>(6<span>x3</span>−2x)</span></span>
<span>=−<span>f<span>(x)</span></span></span>
Thus, the function is odd.
If a function is odd, then it is symmetric over the x-axis.
Answer:
25%

there are 4 cards, and the probability that you choose the one with #5 is 25%
More because it would be starting from 1 then going up to 2 4/5 so that means that he is planning to add music to his playlist.
Answer:
x -7
Step-by-step explanation:
(3x + 5) + (2x - 9) - (4x+3)
3x + 5 + 2x - 9 -4x -3
x -7
Answer:
∠ADB = γ/2 +90°
Step-by-step explanation:
Here's one way to show the measure of ∠ADB.
∠ADB = 180° - (α + β) . . . . . sum of angles in ΔABD
∠ADB + (2α +β) + γ + (2β +α) = 360° . . . . . sum of angles in DXCY
Substituting for (α + β) in the second equation, we get ...
∠ADB + 3(180° - ∠ADB) + γ = 360°
180° + γ = 2(∠ADB) . . . . . . add 2(∠ADB)-360°
∠ADB = γ/2 + 90° . . . . . . . divide by 2

To find angles CXD and CYD, we observe that these are exterior angles to triangles AXB and AYB, respectively. As such, those angles are equal to the sum of the remote interior angles, taking into account that AY and BX are angle bisectors.
