Answer:

Step-by-step explanation:

This means that 12/(2x+1)=8/(x+4). Cross multiply to get 16x + 8 = 12x + 48. Subtract 12x + 8 from both sides to get 4x = 40, so x = 10.

Which expression is equivalent to 1/2x+(−7)−2 1/4x−(−2

Lynna [10]

The equivalent expression to the given expression is $\mathbf{=-(\dfrac{7}{4}x+5)}$

<h3>What is an algebraic expression?</h3>

Algebraic expressions are mathematical expressions. They usually consist of one or more variables with their coefficients and arithmetic operators such as: (division, multiplication, addition, and subtraction).

From the given expression, we are to determine an expression that is equivalent to:

$=\dfrac{1}{2}x + (-7) -2 \dfrac{1}{4}x -(-2)$

To do this, we are going to simplify the above-given expression to its lowest term since we are not given any options to choose equivalent expressions from.

By doing so, we have:

$=\dfrac{1}{2}x -7 -\dfrac{9}{4}x +2$

$=\dfrac{1}{2}x -\dfrac{9}{4}x +2 -7$

$=\dfrac{1}{2}x -\dfrac{9}{4}x -5$

$=-\dfrac{7}{4}x-5$

$\mathbf{=-(\dfrac{7}{4}x+5)}$

Find an exact value.<br><br> <img src="https://tex.z-dn.net/?f=cos%28-%20%5Cfrac%7B%20%5C77%20%5Cpi%20%20%20%20%7D%7B12%7D%29%20

xxTIMURxx [149]

$\cos\left(-\dfrac{7\pi}{12}\right)=\cos\dfrac{7\pi}{12}$

Recall that

$\cos^2x=\dfrac{1+\cos2x}2$

Let $x=\dfrac{7\pi}{12}$ , so that

$\cos^2\dfrac{7\pi}{12}=\dfrac{1+\cos\dfrac{7\pi}6}2=\dfrac{1-\dfrac{\sqrt3}2}2=\dfrac{2-\sqrt3}4$
$\cos\dfrac{7\pi}{12}=\pm\sqrt{\dfrac{2-\sqrt3}4}=\pm\dfrac{\sqrt{2-\sqrt3}}2$

Since the angle $\dfrac{7\pi}{12}$ lies in the second quadrant, you know that the cosine must be negative, so

$\cos\dfrac{7\pi}{12}=-\dfrac{\sqrt{2-\sqrt3}}2$
