Answer:

For the diagram to be a parallelogram, then the measure of x is 4

Step-by-step explanation:

If the diagram is a parallelogram, then the diagonals bisect each other

What this mean is that they divide each other into 2

Mathematically, this means that the values AC is divided into two equal parts AE and CE

That means;

5x + 28 = 3x + 36

5x-3x = 36-28

2x = 8

x = 8/2

x = 4

Questione Simplify Cosa + 2Cos(a +240")

melamori03 [73]

Step-by-step explanation:

$\cos(a) + 2 \cos(a + 240)$

$\cos(a) + 2 \cos(a) \cos(240) - \sin(a) \sin(240)$

$\cos(a) + 2( - \frac{ \cos(a) }{2} + \frac{ \sqrt{3} }{2} \sin(a) )$

$\cos(a) - \cos(a) + \sqrt{3} \sin(a)$

$\sqrt{3} \sin(a)$

If you graph the new identity, and the og identiy, they will be conciding graphs, so they are the same identity.

If f(x)=1/6x+12, then f^-1(x)=<br> PLEASE HELP

Finger [1]

$f(x)=\dfrac{1}{6}x+12\to y=\dfrac{1}{6}x+12$

Change x to y, and y to x.

$x=\dfrac{1}{6}y+12$

solve for y:

$\dfrac{1}{6}y+12=x\ \ \ |-12\\\\\dfrac{1}{6}y=x-12\ \ \ \ |\cdot6\\\\y=6x-72$

Your answer is:

$f^{-1}(x)=6x-72$

Why would negative numbers not make sense for the values of the variables

Naily [24]

One reason that negative numbers would not make sense for values of the variables is that the solution having a negative value is not valid. It might be that the expression represents a real word problem and a negative value will not make any sense. Hope this helps.
