Answer:
I believe the period is 1. Because if it was y= sin2 (2(x-1/2) then the period would be 2.
Answer:

Step-by-step explanation:
We can write the following system of equations:

Adding both equations together, we isolate
and get:

Plugging
in any of the equations, we can solve for
:

Verify that the solution pair
works 
Therefore, the two numbers are
.
Answer:
4x
Step-by-step explanation:
Yes because 26 is an even number
<span>Simplifying
4x + 20 = 6x + -10
Reorder the terms:
20 + 4x = 6x + -10
Reorder the terms:
20 + 4x = -10 + 6x
Solving
20 + 4x = -10 + 6x
Move all terms containing x to the left, all other terms to the right.
Add '-6x' to each side of the equation.
20 + 4x + -6x = -10 + 6x + -6x
Combine like terms: 4x + -6x = -2x
20 + -2x = -10 + 6x + -6x
Combine like terms: 6x + -6x = 0
20 + -2x = -10 + 0
20 + -2x = -10
Add '-20' to each side of the equation.
20 + -20 + -2x = -10 + -20
Combine like terms: 20 + -20 = 0
0 + -2x = -10 + -20
-2x = -10 + -20
Combine like terms: -10 + -20 = -30
-2x = -30
Divide each side by '-2'.
x = 15
Simplifying
x = 15</span>
