Factor -1/2 out of -1/2 X +6=?
solong [7]
The solution to the problem is as follows:

Since -1/2 is the greatest common factor of the two terms,

(-1/2)x + 6 = (-1/2) (x - 3)

The factored form therefore is (-1/2) (x - 3). I hope my answer has come to your help. God bless and have a nice day ahead!

How do I write 23/50 as a decimal?
masha68 [24]
A fraction is just a short way to write a division problem.

Every fraction really means

                       (the top number) divided by (the bottom number).

When you actually do the division, the quotient is the decimal for the fraction.

To find the decimal for 23/50,  divide 23 by 50 .

Let t = cosA + sinA<br> find values of t if <br> 2 - sin2A = 2(cosA + sinA)
Zinaida [17]

2 - \sin(2A) = 2(\cos A + \sin A)\\\\2-2\sin A\cos A=2\cos A+2\sin A\\\\2\sin A\cos A+2\cos A+2\sin A-2=0\\\\1+2\sin A\cos A+2\cos A+2\sin A-3=0\\\\\sin^2 A+\cos^2 A+2\sin A\cos A+2\cos A+2\sin A-3=0\\\\(\sin A+\cos A)^2+2\cos A+2\sin A-3=0\\\\(\sin A+\cos A)^2+2(\cos A+\sin A)-3=0\\\\\\t^2+2t-3=0\\\\t^2+2t+1-4=0\\\\(t+1)^2=4\\\\t+1=2\qquad\vee \qquad t+1=-2\\\\\\\boxed{t=1\qquad\vee\qquad t=-3}

When A\in\mathbb{R}

t=\cos A+\sin A\in[-\sqrt{2};\sqrt{2}]\approx[-1.4142;1.4142]

and there is only one answer t = 1.

For A\in\mathbb{C} both values are correct.
