Answer:
(-3+) /2, (3+) / 2 which is approx -3.791 and 0.791
Step-by-step explanation:
i used the quadratic formula: [-b± sq rt (b² - 4ac) / 2a]
in this problem, a = 1, b = 3, and c = -3
Answer: I'm pretty sure its a or the first one ^w^
Step-by-step explanation:
Asuuing yo meant (h,k)=(-5,1/2)
equation is
(h,k) is center and r=radious
given that (h,k)=(-5,1/2) and r=1
h=-5
k=1/2
if you wanted us to expand
x
²+y^2+10x-y+25.25=1
4x+5y=7
y=3x+9
1) 4x+5(3x+9)=7 2) y=3(-2)+9
y= -6 +9
4x+15x+45=7 y=3
19x+45=7
19x= -38
x= -2
x is -2 and y is 3
Answer:
32
Step-by-step explanation:
The sides of the quadrilateral are tangents to the circle.
Tangents drawn from an external point to the circle are congruent
5+5+4+4+3+3+4+4=32
