From 14-21 you have to do it by a calculator and then put it between perfect numbers then minus the bigger perfect number by it and if needed graph on a number line
Answer:
x=28
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
Start by using the distance formula to find the raidus
The two points are (-2,1) and (-4,1)
√((-4+2)²+(1-1)²)= 2
The radius is two and we have our center which means we can write
(x+2)²+(y-1)²=4
now it's just a matter of expanding everyhting
x²+4x+4+y²-2y-3=0
x²+y²+4x-2y+1=0
This is equal to B
Ok you must do the inverse of division which is multiply
