Complete the square
since a=1 for ax²+bx²+c=0
we can do
take 1/2 of the linear coefient and square it
-6/2=-3, (-3)²=9
add that to both sides
x²-3x+9-25=9
factor perfect square trinomial
(x-3)²-25=9
add 25 to both sides
(x-3)²=34
sqrt both sides, rmember to take positive and negative roots
x-3=+/-√34
add 3
x=3+/-√34
x=3+√34 or 3-√34
Answer:
Answer D :
The multiplicative inverse is equal to v(x), but the additive inverse is not.
Answer:
y-5=1/4(x-3)
Step-by-step explanation:
first you need to find the slope.
5-7 over 3-6 = -1/-4 or 1/4
next put into point-slope form.
y-y1=m(x-x1)
or y-5=1/4(x-3)

Hope this helpsss
i will bite - this is not a complete ans but an approximation:
there are 100*99*98 ways to pick 3 different no. out of 100
if 2 of the no. picked are >10, then there is no way the third no. can be larger than the products of the other 2 nos.
there are 90*89*98 ways to pick 2 nos between 10 and 100 and a third no. between 1 and 100.
So an approximate ans = 100*99*98 - 90*89*98 = 185220 but the actual ans will be smaller than this.
