Answer
7,0
Step-by-step explanation:
Substitute -6y+7 into problem one where the x is
distribute the 2 and subtract the 9 y and you will get
-21y+14=14
subtract 14 from both sides and it will be -21y=0 so y will be 0
substitute the 0 into equation 2 and find x=7
Answer:
The possible coordinates of point A are
and
, respectively.
Step-by-step explanation:
From Analytical Geometry, we have the Equation of the Distance of a Line Segment between two points:
(1)
Where:
- Length of the line segment AB.
- x-coordinates of points A and B.
- y-coordinates of points A and B.
If we know that
,
,
and
, then the possible coordinates of point A is:




There are two possible solutions:
1) 

2) 

The possible coordinates of point A are
and
, respectively.
Answer:
The correct option is 1. The area of cross section area is 48 mm².
Step-by-step explanation:
From the find it is noticed that the cross section is a rectangle with length 4 mm and width is 12 mm.
The area of a rectangle is the product of its dimensions.

Where, l is length of the rectangle and w is width of the rectangle.
The area of cross section is


Therefore the area of cross section area is 48 mm². Option 1 is correct.
