-b-2>8
add 2 to both sides
-b>10
multiply both sides by -1
b>-10
Answer:
It could be 11/10
Step-by-step explanation:
<span>Three powers with whole number bases that have values greater than 120 and less than 130 are:
</span>11² = 11 x 11 = 121
<span>5³ = 5 x 5 x 5 =125 </span>
<span>2⁷ = 2 x 2 x 2 x 2 x 2 x 2 x 2 = 128
</span>
<span> we have that
standard form of equation for parabola:
(x-h)^2=-4p(y-k)
(h,k) --------->being the (x,y) coordinates of the vertex.
Parabola opens downwards because focus is below vertex on the axis of symmetry.
For given problem:
</span><span>vertex: (-3,2)
axis of symmetry: x=-3
p=distance from vertex to focus on the axis of symmetry=2-(-1)=3
4p=12
Directrix: y=2+p=5
Equation:
(x+3)^2=-12(y-2)
the answer is </span>(x+3)^2=-12(y-2)
