Answer: (-3,0)
To get this answer, we subtract 5 from the x coordinate and add 2 to the y coordinate. Point A is located at (x,y) = (2,-2) so we see that x = 2 and y = -2
Subtract 5 from the x coordinate: x-5 = 2-5 = -3. The new x coordinate is -3
Add 2 to the y coordinate: y+2 = -2+2 = 0. The new y coordinate is 0.
Therefore, using the rule (x,y) --> (x-5,y+2) has the mapping (2,-2) ---> (-3,0)
Check out the attached image.
This is a vertical line. Vertical lines are composed by points who share the same x coordinate.
That's why the equation of the line is exactly
, where k is the shared x coordinate.
In your case, the common x coordinate is 3, so the line is 
Answer: 40
Step-by-step explanation:
Answer:
boys 5:2 girls
add the ratio parts together
5 + 2 = 7
divide the total number of students by the total number of parts
35/7 = 5
now multiply each part of the ratio by 5
boys 25
girls 10
there are 25 boys
