The position of the trout now relative to the surface is -17 feet. Therefore, Denis is wrong.
<h3>What is an expression?</h3>
It should be noted that a expression shows the relationship between the variables.
From the information, a trout was swimming 9 feet below the surface of a lake and it drove down 8 more feet to search for food.
The position will be the addition of the feets. This will be:
= -9 + (-8)
= -9 - 8
= -17 feet
The position is -17 feet.

Answer:
This can be done in stages: To calculate the millilitres/hour we first need to work out what dose is contained in one millilitre of the infusion dosage. We can do this by dividing the volume of the dosage by the weight of the medicine it contains. In this case 500ml/500mg = 1ml/mg.Step-by-step explanation:
The independent variable would be x, as it depends on nothing to determine its value. The dependent variable is f(x), as it depends on x to determine its value. This means we plug -4 into x and solve the equation to find f(x).
f(x) = -5(-4) + -4/-2
f(x) = 20 + 2
f(x) = 22
So the answer is C.
The y-intercept can be found when you look where in the graph that the line crosses the y-axis.
If you were given an equation, you would plug in x = 0, to find the y-intercept.
In the graph, you can see that the line crosses at the point (0,-1).
Therefore, the y-intercept is -1.
Change the - to sum
x+-2y=8
The second one to the opposite
And x is 2 and y is 2 so
It’s 2+2 is 4 and 4 multiplied by 2 is 8
I hope I am correct, good luck! :)
