Answer:
(2,-5) and (2,1).
Step-by-step explanation:
We need to find the find all the points having an x coordinate of 2 whose distance from the point (-2,-4) is 5.
A circle with center (-2,-4) and radius 5 represents all the points whose distance from the point (-2,-4) is 5.
Standard form of a circle is

where, (h,k) is center and r is the radius.


Now, put x=2.




Taking square root on both sides.




So, the y-coordinates of the points are -5 and 1.
Therefore, the required points are (2,-5) and (2,1).
Answer:
You can use a number line to subtract -6 from -7. The difference is -1.

Answer:
x=4 y=6
Step-by-step explanation:
12 divide by 3 = 4
12 divide by 2 = 6
3x² + 9x - 54 :(3)
x² + 3x - 18
(x-3)*(x+6)
