See below for the description of changes when the dependent and the independent variables are switched

<h3>How to determine the changes?</h3>

<u>The table of values</u>

When the dependent and the independent variables are switched, the values also become switched on the table.

This means that the table becomes an inverse table of the function

<u>The scatter plot</u>

Switching the variables implies that the original function is being reflected across the line y = x

<u>The description in words</u>

This description is an inverse relation of the original function

<u>The equation</u>

This description is an inverse equation of the original function.

If the initial equation is y = ax + c, the new equation becomes x = ay + c

During his surgery, Farak's doctor controlled a robot with a joystick. Every time the doctor moved her

Zinaida [17]

Answer:

Linear

Step-by-step explanation:

The definition of linear is "the property of a mathematical relationship that can be graphically represented as a straight line." If the robot arm moved 1/4 inch every time the controller is moved 1/4 inch. That means the relation is linear. This is because if the controller was moved 1 inch, the robot would move 1 inch. This relation is shown in the graph below, the equation is y = x.

Solve this quadratic equation by completing the square.

nadya68 [22]

Answer:

$x=-3+\sqrt{27}\\ x=-3-\sqrt{27}$

Step-by-step explanation:

Let's find our C value for the quadratic equation.

$(\frac{6}{2})^{2} = 9$

That is our C. Since we added 9 to one side, we have to do the same to the other. We get:

$x^{2} +6x + 9 = 18 + 9\\x^{2} +6x + 9 = 27$

Now, lets form the left side as a binomial squared.

$(x+3)^{2} = 27$

Let's square both sides now:

$x+3 = (+/-)\sqrt{27}$

Now, we subtract 3 from both sides to isolate the variable, X:

$x= -3(+/-)\sqrt{27}$

This means that the answers are:

$x=-3+\sqrt{27}\\ x=-3-\sqrt{27}$

I do not understand your answers though. Answer A makes no sense, answer B is 221, answer C is 115, and answer D also does not make sense. If you could clarify this portion, maybe I can help you find your alphabetic answer

3 The formula to find the area of a rectangle is A = lw. If l = 6 in and w = 5 in, then what is the area of the blue portion of

Serga [27]

Answer:C. 15

Step-by-step explanation:

Its 15 because the rectangle is 30 and the blue side is half of it so you would have to divide 30 by 2

30 ÷ 2 = 15
