Answer:

366.

-1493.

Step-by-step explanation:

54.8-6.9-12

You perform the multiplications first:

= 432 - 54 - 12

= 378 - 12

= 366.

5-2.83.9-4

= 5 - 166* 9 - 4

= 5 - 1494 - 4

= -1489 - 4

= -1493

Rectangle PQRS is rotated 90 counterclockwise about the origin what are the coordinates of point Q

inna [77]

You have not provided the diagram/coordinates for point Q, therefore, I cannot provide an exact answer.
However, I can help you with the concept.

When rotating a point 90° counter clock-wise, the following happens:
coordinates of the original point: (x,y)
coordinates of the image point: (-y,x)

Examples:
point (2,5) when rotated 90° counter clock-wise, the coordinates of the image would be (-5,2)

point (1,9) when rotated 90° counter clock-wise, the coordinates of the image would be (-9,1)

point (7,4) when rotated 90° counter clock-wise, the coordinates of the image would be (-4,7)

Therefore, for the given point Q, all you have to do to get the coordinates of the image is apply the transformation:
(x,y) .............> are changed into.............> (-y,x)

Hope this helps :)

Answer:

$\huge \boxed{\mathrm{C}}$

Step-by-step explanation:

The domain is the set of all possible values for x.

The function does not cross the line x = 1.

The domain is all real numbers except 1.

The range is the set of all possible values for y.

The function does not cross the line y = 0.

The range is all real numbers except 0.

Find the range of the function:<br><br> f(x) = x + 3, for x ≠ 1

Tju [1.3M]

Answer:

All Real Numbers except for 4

Step-by-step explanation:

Objective: Specify domain and range of a function.

The equation is a linear equation. A linear equation range is all real numbers. However x cannot equal 1 so let plug in x to find where the y value CANT be.

$f(1) = 1 + 3 = 4$

So the range is

All Real Numbers except for 4.
