Rewrite equation to solve for m 4n-6m=-2
hram777 [196]

Answer:

Step-by-step explanation:

4n - 6m = - 2              Subtract 4n from both sides.

4n-4n - 6m = -2-4n

-6m = - 2 - 4n             Divide by - 6

-6m/-6= -2/-6 -4n/-6  Do the division

m = 1/3 + 2n/3

The signs change because each term has 2 minus signs. 2 minus signs make a plus. Or both minus signs cancel.

Cos3x=4cos^3x-3cosx prove
IgorC [24]
\bf cos(\alpha + \beta)= cos(\alpha)cos(\beta)- sin(\alpha)sin(\beta)
\\\\\\
\textit{also recall that }cos(2\theta)=
\begin{cases}
cos^2(\theta)-sin^2(\theta)\\
1-2sin^2(\theta)\\
\boxed{2cos^2(\theta)-1}
\end{cases}
\\\\\\
and\qquad sin^2(\theta)+cos^2(\theta)=1\implies sin^2(\theta)=1-cos^2(\theta)\\\\
-------------------------------

\bf cos(3x)=4cos^3(x)-3cos(x)\\\\
-------------------------------\\\\
cos(3x)\implies cos(2x+x)\implies cos(2x)cos(x)-sin(2x)sin(x)
\\\\\\\

2cos^3(x)-cos(x)~~~~-~~~~2[1-cos^2(x)]cos(x)
\\\\\\
2cos^3(x)-cos(x)~~~~-~~~~[2cos(x)-2cos^3(x)]

Options are A. 17 B. 50 C. 19 D.21
ad-work [718]

Answer:

C. 19

Step-by-step explanation:

BD = DC because angles ADC and ADB are right angles.

Thus, 4x-5=2x+7

Add 5 to both sides:

4x-5+5=2x+7+5

4x=2x+12

Subtract 2x from both sides:

4x-2x=2x+12-2x

2x=12

Divide both sides by 2:

\frac{2x}{2}=\frac{12}{2}

x=6

DC =4x-5

=4(6)-5

=24-5

=19
