In preparation of yourself in having to teach numeracy, it
is best to substantiate if learning the numeracy will have benefits or
advantages, such as having to help other people or even empower them as an
adult people learning and think of ways how will this could be important to
them.
Answer:
k = -2
Step-by-step explanation:
2 way to solve:
1st: 8x²-13x-4k = 8(x²-(13/8)x-(k/2))
if 2 roots: a and 1/a
8(x-a)(x-1/a) = 8(x²-(13/8)x-(k/2))
x²-(a+1/a)x+1 = x²-(13/8)x-(k/2)
1 = -(k/2)
<u>k = -2</u>
<u>2nd:</u> 2 roots of 8x²-13x-4k x=(-b±√b²-4ac)/2a
x = (13±√169-4*8*(-4k))/16 = (13±√169+128k)/16
(13+(√169+128k))/16 = 16/ (13-(√169+128k)) ... root1=1/root2
(13+(√169+128k))*(13-(√169+128k)) = 16*16
13² - (√169+128k)² = 256
169-169-128k = 256
-128k = 256
k = -2
Dividing is the opposite of Multiplying.
If you multiply 9 * 1 = 9.
So if you Divide N by 9 the answer would be 1.
I hope this helped. ^_^
