If G^-1(x) is the inverse of G(x), what is the value of G^-1(G(x))?

Ber [7]

Answer:

$G^{-1}(G(x))=x$

Step-by-step explanation:

Definition: Let f be one-to-one function with the domain A and the range B. Then the inverse function $f^{-1}$ has the domain B and the range A and is defined as

$f^{-1}(y)=x\ \Leftrightarrow \ f(x)=y$

Facts:

1) For every $x\in A:$

$f^{-1}(f(x))=x$

2) For every $y\in B:$

$f(f^{-1}(y))=y$

So, $G^{-1}(G(x))=x$

Given segment AB with points (-4, 8) and (6, 3) respectively. Find the coordinates of point P that partitions Segment AB in the

netineya [11]

Answer:

$P = (2,5)$

Step-by-step explanation:

Given

$A(-4,8)$

$B(6,3)$

$m:n = 3 : 2$

Required

Determine P

Since P divides the segment into 3:2, P is calculated using

$P = (\frac{nx_1 +m x_2}{m+n},\frac{ny_1 + my_2}{m+n})$

Where

$(x_1,y_1) = (-4,8)$

$(x_2,y_2) = (6,3)$

$m:n = 3 : 2$

Substitute these values in the above formula:

$P = (\frac{2 * -4 +3 * 6}{3 + 2},\frac{2 * 8 + 3 * 3}{3 + 2})$

$P = (\frac{-8 +18}{3 + 2},\frac{16 + 9}{3 + 2})$

$P = (\frac{10}{5},\frac{25}{5})$

$P = (2,5)$

the factors of x²+kx+8 are(x+a)(x+b), where a and b are integers. show that there are two possible values of k

Sladkaya [172]

I hope this helps you

x.x+x.b+x.a+a.b

x^2+(b+a).x+a.b

a.b=8

a=1 b=8

a+b=k

k=1+8=9

a=2 b=4

k=2+4=6

a= -1 b= -8

k= -1-8=-9

a= -2 b= -4

k= -2-4=-6
