After you type in your equations and hit graph you notice that, if you are in the standard window, your parabola is cut off so you have to choose your "window" button to change the viewing window to see the whole graph. Then you would use your 2nd button and "trace" and "intersect" to find the points of intersection of the 2 graphs. The first point is at (-.90901, 16.81812) and the second point is at (5.9090909, 3.1818182). Graphing calculators are quite amazing!
I believe the 2 ways would be

and

and this equation is significant because it is the perimeter formula
Step-by-step explanation:
y=-3/4 ÷ -4/3
y=+9/16
It's C. The congruence statement tells you what parts of rhe polygon are congruent to each other, so basically which will have the same measure. In the statement, you can tell that PS is congruent to JL because theyre in the same "positions", just on opposite sides of the equal sign.
Answer:
Step-by-step explanation:
Ok so the beaker is 200 water:800 acid
So she drains 100 from the acid and 100 from the water which equals

Then she adds 200 water:
300:700
there is 300 mL water in da beaker now
i might got it wrong tho
