Answer: The "independent variable" is the "time" (in hours) that is plotted on the "x-axis". Note the "time" (in hours) can be "manipulated" in the sense that is it "chosen" by the humans who are measuring the data (e.g. when to start, how many hours, and at what intervals.
The "dependent variable" is the measurement (in feet) above or below the sea level, and this is plotted on the "y-axis". These values cannot be "manipulated" in the sense that one cannot "choose" what value or measurement the tide level would be at any particular time.
Hope these answers—and explanations—are of help to you.

Answer:
3x^2 + xy - 10y^2
Step-by-step explanation:
1. Use the FOIL method
3x
^2 − 5xy + 6yx − 10y
^2
2. Collect like terms
3x
^2
+ (−5xy + 6xy) − 10y^2
3. Simplify
3x
^2
+ xy − 10y^2
Answer:
plot points (0, -1) and (3, 0)
Step-by-step explanation:
compare the given equation to
y=mx +b where b is the y-intercept
y= 1/3 x -1 so thhe y-intercept is at point (0, -1)
to find the x-intercept make y=0
x/3 -1 =0
x/3 =1
x= 3 so x-intercept is at point (3, 0)
