Answer:

The answer is  cos2x - sin2x - sin x.

Use the rule: cos2x = (cos^2)x - (sin^2)x. So, substitute cos2x in the expression: cos2x - sinx = ((cos^2)x - (sin^2)x) - sinx = (cos^2)x - (sin^2)x - sinx.

Hope it helps

Please mark me as the brainliest

Thank you

zavuch27 [327]
So first I hope this helps! But from what I’ve learned in school is that a unit rate pretty much just mean *1... so in words the answers would be 1/6 and hour for every 2/23 miles

Given the linear equation 2x + y = 6, perform the necessary operations to put the equation into the proper general form. Explain
likoan [24]

Step-by-step explanation:

The general equation is y = mx + c...

The given equation is 2x + y = 6

Firstly, move everything on the left except the y to the right.i.e.

y = 6 - 2x

Secondly, rearrange the values on the right to look just like the general equation.

y = -2x + 6

The equation is now in proper general form because it matches the format laid down.

[2/(n+2)] - (3/n+2) = 5<br><br> Solve by u-substitution
IgorLugansk [536]
<span>let n+2=u so, the equation became= [2/u]-[3/u]=5 => [(2+3)/u]=5 => 5/u=5 => u=5/5=1 thus, u=1 we know u=n+2 so, n+2=1 => n=1-2=-1 so, n=-1</span>
