When solving the equation, which is the best first step to begin to simplify the equation?
-2(x+3) --10
(-2)-2)(x+3) --10(-2)
• (-2)(x+3) --10(-1)
• ž(x+3) = -40
(x+3) =10
save and exit
mark this and return

To simply a equation you need to use Pemdas

the order of operations.

We need to simplify parethesis first...

if you cant simplify in it like (x+3)

you need to use the distributive property

-2 *x

-2*3

Period is the time it takes for one “cycle” to complete. in the parent sine function, period is 2*pi since sin(0) = 0, sin(pi/2) = 1, sin(pi) = 0, sin(3pi/2) = -1, and sin(2pi) = 0. at that point, the sequence repeats itself. i’m not sure if your graph is similar to the sine function since you didn’t provide a picture, but you can find the period by looking at a graph.
