Answer:
x = 8
x = -10
Step-by-step explanation:
10.5 divided by 8 should be 1.3125
Answer:
0.032
Step-by-step explanation:
.008/.25
Use a calculator or do it on google
X2+5x+y2-y=-2
X2+2*5x2+(5/2)^2-(5/2)^2+y2-2*y/2+(1/2)^2-(1/2)^2=-2
(x+5/2)^2+(y-1/2)^2-13/2=-2
(x+5/2)^2+(y-1/2)^2=9/2
So centre =(-5/2,1/2)
Radius=(9/2)^(1/2)
90 degrees should be right
