Wasn’t able to get the answer Buh I hope you the best of luck bestie
Answer:
The last equation x2 - 2x -4 = 0
has solution (x - 1)^2 - 5 = 0, x = 1 + root(5) or x = 1 - root(5)
Step-by-step explanation:
If a quadratic function has roots 1 and 5
f(x) = (x -1)(x- 5)
f(x) = x^2 - 6x + 5
Unless you meant. -4 and 6 ?
g(x) = (x + 4)(x - 6)
g(x) = x^2 -2x -24
-------------------------
Or did you mean x = 1 and x =4 ?...
x^2 + 2x + 4 = 0 : complete square x^2 + 2x + 1 + 3 = 0, (x+1)^2 + 3 = 0
x^2 - 2x + 4 = 0 : complete square: (x -1)^2 + 3 = 0
0x^2 + 2x - 4 = 0, 2x - 4 = 0, x = 2
x^2 - 2x - 4 = 0 becomes: x^2 - 2x + 1 - 1 -4 = 0 ; (x - 1)^2 - 5 = 0
Answer:
I think the answer would be 33. I am not exactly sure though.
<span>Answer = probability that he selects exactly 2,3,4 or 5 passing plays.
prob that he selects exactly two passing plays =
(8C2)*(9*8)*
(15*14*13*12*11*10)
/(26*28*.....19)
where:
8C2 is the number of ways of choosing two slots out of 8 and
prob that he selects first passing play = 9/26
prob that he select second passing play = 10/25 etc
you can calculate the other three cases similarly and sum to obtain the answer.</span>
Answer:
2x - 4
Step-by-step explanation:
x + 10 + x - 14
2x + 10 - 14
2x - 4
