I think like that but I’m not sure
Answer:
To quickly solve this problem, we can use a graphing tool or a calculator to plot the equation.
Please see the attached image below, to find more information about the graph.
K, so since directix is below focus, it opens up (2<4)
and directix is y=something so equation is (x-h)^2+4p(y-k) where (h,k) is vertex and p is distance from focus to vertex. if it opens down, p<0, if it opens up, p>0
and the vertex is in the middle of the focus and directix
so
distance bewten (-2,4) and y=2 is 2 units
2/2=1, so 1 unit down from focus
vertex is in the middle so it is at (-2,3)
also, opens up so p=1
vertex (-2,3)
p=1
(x-(-2))^2=4(1)(y-3)
(x+2)^2=4(y-3) is an equation
Set it up algebraically
3 times a number so 3x where x = the mystery number
times 7 so 3x*7
and it equals 63 so,
3x*7=63
this can be further simplified to
21x=63
then just divide both side by 21 to get your answer
(21/21)x=(63/21)
so x=3
Answer:
<h2>(0.5, 0.5)</h2>
Step-by-step explanation:
The formula of a midpoint of a segment AB with endpoints at A(x₁, y₁) and B(x₂, y₂):
From the graph we have the points A(-2, 4) and C(3, -3).
Substitute:
