Text my number ( 4015166761) i did all of that already im in 7th ill hook u up wit all the answers .
Answer:
Step-by-step explanation:
<u>Function given:</u>
Evaluate the function for an input value of 3
<u>Input value is x = 3, output value is:</u>
- f(3) = -4(3²) – 3(3) – 5 = -4(9) - 9 - 5 = -36 - 14 = -50
- f(3) = -50
The possible outcomes where the red die shows a 3 are: (red, blue) = (3, 1), (3, 2), (3, 3), (3, 4), (3, 5), (3, 6).
Answer:
If the equation ends with a false statement (ex: 0=3) then you know that there's no solution. If the equation ends with a true statement (ex: 2=2) then you know that there's infinitely many solutions or all real numbers.
Step-by-step explanation:
I hope this helps you out! :)
Yay
directix x=5
that means the parabola opens left or right
the equation is
(y-h)²=4p(x-h)
alrighty
vertex is (h,k)
p is distance from focus to vertex
also distance from vertex to directix
if p>0 then the parabola opens to the right and focus is to the right of directix
if p<0 then the parabola opens to the left and focus is to the left of directix
alrighty
the distance between directix and focus divided by 2=p
hmm, note which one is to the left or right of which
directix is x=5
focus is (2,-3) where x=2
focus is to the left of directix
alrighty
fro m 5 to 2 the distance is 3
3/2=1.5
and since the focus is to the left of the directix, it is -1.5
so the parabols opens to the left
the vertex is 1.5 untis to the right of the focus
so vertex is at (3.5,-3)
so
equation is
(y-(-3))²=4(-1.5)(x-3.5)
(y+3)²=4(-1.5)(x-3.5)
