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: Scott reads 9 chapters per hour.
Step-by-step explanation:
63/7 = 9
That would be 2 numbers. they are 10 and -10.
X + y = 136
x = 3y - 16
3y - 16 + y = 136
4y - 16 = 136
4y = 136 + 16
4y = 152
y = 152/4
y = 38
x = 3y - 16
x = 3(38) - 16
x = 114 - 16
x = 98
the larger piece (x) = 98 ft and the smaller piece (y) = 38 ft
Answer:
y = 1x + 6
Step-by-step explanation:
y = 1x + b
-1 = 1(-7) + b
-1 = -7 + b
6 = b
