Answer:
The coordinates of point R are (7,6), second option
Step-by-step explanation:
Coordinates of point R:
The coordinates of point R are , so (6,-7).
90° counterclockwise rule:
The rule for a rotation of 90º counterclockwise is given by:
(x,y) -> (-y,x)
What are the coordinates of point R?
(6,-7) -> (-(-7),6) = (7,6).
The coordinates of point R are (7,6), second option
Answer:
The answer is neither.
Step-by-step explanation:
We need to solve for y in the equation, 10x-2y= 6.
In other words, we are going to find the slope intercept of that equation.

So we have now have both the equations:

It's not parallel because the slopes aren't the same. It's not perpendicular because when the slope of the equation becomes a negative reciprocal, it still doesn't end up with the same slope as the other equation.
It's neither parallel or perpendicular.
Answer:
2x - 3
Step-by-step explanation:
The are of a rectangle is computed using the formula:
A = L x W
The area given is:
2x² + 5x -12
So:
2x² + 5x -12 = L x (x + 4)

So we can solve this through division:
<u> 2x - 3 </u>
x + 4 | 2x² + 5x - 12
<u> - 2x² + 8x </u>
-3x - 12
<u>- -3x - 12</u>
