The correct answer will be A 40
I would say the answer is b, because it is a rhombus gape and all sides are congruent and there are 4 sides
The regular period is 2pi. If you look up or type in a graphing calculator you can see that's when the sine function starts to repeat itself.
As you know, 4.78 is less than 5, so
.. yes, x=4.78 is a solution to x < 5
As you know, 6 = 6, but is not less than 6.
.. no, x=6 is not a solution to x < 6.
Answer:
Move all terms that don't contain x to the right side and solve.
x = −2
