Simple...this is a discount problem.
To find the answer to this problem you can find the net price percentage of the shoes by doing...
100%-33%=67%
Now...multiply the original price by the net price percentage...
$42*0.67=$28.14
Thus, the shoes after the discount cost, $28.14
Girl I’m sorry but do u mean question ? ♀️ and its the third one I think
The expression that is not equivalent to (1 - sin²(x)) tan(-x) is D. (cos²x - 1)(cot -x).
<h3>How to illustrate the expression?</h3>
It should be noted that (cos²x - 1)(cot -x). is not equivalent to the given expression.
This is illustrated as:
(cos²x - 1)(cot -x)
= (-sin²x) × (-cot x)
= sin²x × cosx/sin x = sinxcosx
In conclusion, the correct option is D.

The expression _______ is not equivalent to (1 − sin2(x)) tan(-x).
a. (1 - cos^2(x)) cot(-x)
b. (cos^2(x) - 1) cot(x)
c. (sin^(x) - 1) tan(x)
d. (cos^2(x) - 1) cot(-x)
can be added to
to make it equivalent to
.
Step-by-step explanation:
Let,
y be the term that can be added to given fraction.
Therefore;
![(\frac{5}{6}x-4)+y=\frac{1}{2}x-4](https://tex.z-dn.net/?f=%28%5Cfrac%7B5%7D%7B6%7Dx-4%29%2By%3D%5Cfrac%7B1%7D%7B2%7Dx-4)
Subtracting
from both sides to find y
![(\frac{5}{6}x-4)-(\frac{5}{6}x-4)+y=\frac{1}{2}x-4-(\frac{5}{6}x-4)\\\\\frac{5}{6}x-4-\frac{5}{6}x+4+y=\frac{1}{2}x+4-\frac{5}{6}x+4\\\\y=\frac{1}{2}x-\frac{5}{6}x\\\\y=\frac{3-5}{6}x\\\\y=\frac{-2}{6}x\\\\y=\frac{-1}{3}x](https://tex.z-dn.net/?f=%28%5Cfrac%7B5%7D%7B6%7Dx-4%29-%28%5Cfrac%7B5%7D%7B6%7Dx-4%29%2By%3D%5Cfrac%7B1%7D%7B2%7Dx-4-%28%5Cfrac%7B5%7D%7B6%7Dx-4%29%5C%5C%5C%5C%5Cfrac%7B5%7D%7B6%7Dx-4-%5Cfrac%7B5%7D%7B6%7Dx%2B4%2By%3D%5Cfrac%7B1%7D%7B2%7Dx%2B4-%5Cfrac%7B5%7D%7B6%7Dx%2B4%5C%5C%5C%5Cy%3D%5Cfrac%7B1%7D%7B2%7Dx-%5Cfrac%7B5%7D%7B6%7Dx%5C%5C%5C%5Cy%3D%5Cfrac%7B3-5%7D%7B6%7Dx%5C%5C%5C%5Cy%3D%5Cfrac%7B-2%7D%7B6%7Dx%5C%5C%5C%5Cy%3D%5Cfrac%7B-1%7D%7B3%7Dx)
