I think the answer is 78 because more usually mean addition so 57+21=78
Answer:
0.74
Step-by-step explanation:
We can isolate x, getting 9.2x - 1.9x = -1 + 6.4
We can then simplify, getting 7.3x = 5.4, which we can solve by dividing both sides by 7.3:
x = 5.4 / 7.3 = 0.74
Answer:
40 is your correct answer
Answer:
c
Step-by-step explanation:
<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)
