Answer:

1+cos^2(2A)=(1−cos2(2A))+2cos^2(2A)

=sin^2(2A)+2(cos^2A−sin^2A)^2

=(2sinAcosA)^2+2(cos^4A−2cos^2Asin^2A+sin^4A)

=2(cos^4A+sin^4A)

slope intercept form of equation of a line that passes through (-3,8) y=-2/3x+6 what is the point slope equation for this line??
nlexa [21]

Answer:

\large\boxed{y-8=-\dfrac{2}{3}(x+3)}

Step-by-step explanation:

The slope-intercept form of an equation of a line:

y=mx+b

m - slope

b - y-intercept

The point-slope form of an equation of a line:

y-y_1=m(x-x_1)

We have the equation of a line in the slope-intercept form

y=-\dfrac{2}{3}x+6\Rightarrow m=-\dfrac{2}{3}

and the point (-3, 8).

Substitute:

y-8=-\dfrac{2}{3}(x-(-3))\\\\y-8=-\dfrac{2}{3}(x+3)
