Answer:
Option D. x ≥ -4
Step-by-step explanation:
____________
Sinx=1/2
sin30=1/2
therefore x=30 degree
Answer:
The correct method for recording numerical information from an experiment is the quantitative method.
Step-by-step explanation:
This method represents the way of recording that tracks variables (sometimes more than one) and how they interact with each other. This will help to establish relationship within your experiment.
X=5 y=15 (5,15).
This is how you do it:
-4(2x+3y=55): -8x-12y=-220
3(9x+4y=105):27x+12y=315
You add the two new equations together, canceling out the y values, and get the x value. Then, you go back and plug in the x value in the original equation to get the y value.
Im pretty sure that it would be 600%. If it was 600% that would be 600 over 100 which would be 6
