Answer:  C

Step-by-step explanation: Because The graph of y = x - 3 is a translation of y = x by three units down, every x-coordinates on the equation y = x is to be decreased by 3 units. Also, It is y=x-3 so the answers B and D are eliminated since they say it is translated upwards. Also, since it is x-3 it is less than the output of y=x, so A is eliminated. The only option left is C.

Answer:

The correct option is C.

Step-by-step explanation:

The given functions are

y=x             ... (1)

y=x-3         .... (2)

The translation is defined as

y=x+b                .... (3)

If b>0, then the graph shifts b units up and if b<0, then the graph shifts b units down.

From (2) and (3) we get b=-3. It means the graph of y = x translated down 3 units to get the graph of y = x - 3.

Output of first function is equal to x and output of second function is x-3. It means each output for y = x - 3 is 3 less than the corresponding output for y = x.

Therefore the correct option is C.

Ainat [17]

The area of the figure created by Verona is 96.56 cm²

<h3>Area</h3>

Area is the amount of space occupied by a two dimensional object.

The area of the circle = (1/4) * π * 4² = 12.56 cm²

The area of the square = 8 cm * 8 cm = 64 cm²

Area of the triangle = (1/2) * 8 cm * (17 - 8 - 4) = 20 cm²

Area of the figure created by Verona = 12.56 + 64 + 20 = 96.56 cm²

The area of the figure created by Verona is 96.56 cm²
