\bf \textit{Double Angle Identities}
\\ \quad \\
sin(2\alpha)=2sin(\alpha)cos(\alpha)
\\ \quad \\
\boxed{cos(2\alpha)=
\begin{cases}
cos^2(\alpha)-sin^2(\alpha)\\
1-2sin^2(\alpha)\\
2cos^2(\alpha)-1
\end{cases}}
\\ \quad \\
tan(2\alpha)=\cfrac{2tan(\alpha)}{1-tan^2(\alpha)}

Find the equation of the line.<br> Use exact numbers.<br> y=
Sergio039 [100]

Answer:

y = 2x+4

Step-by-step explanation:

First we need to find the slope using two points

(-2,0) and (0,4)

m = (y2-y1)/(x2-x1)

m = (4-0)/(0--2)

   = 4/+2

   = 2

we have the y intercept  which is 4

Using the slope intercept form of the line

y = mx+b where m is the slope and b is the y intercept

y = 2x+4

Please please help worth lots of points Given ƒ(x) = x - 1, complete Parts A and B. Part A: Using the table provided, create fiv
Gemiola [76]
Wouldn’t you just for part a, insert different x values and solve to get your y value. and do that over and over again with different numbers to create a data table. and then for part b you’ll just make a graph and put down the points. so for the first slot, do 0 for x. y will equal -1 after solving, so your first plot for part b can be (0,-1) and continue on from there
