Answer:

1/2

Step-by-step explanation:

5/10 = 0.5

0.5 = 4/8 = 3/6 = 2/4 = 1/2.

Whenever you see a fraction where the denominator is exactly twice as big as the numerator, you know that it equals 0.5 or the other fractions that equal 0.5

$\\ \sf\longmapsto \dfrac{8}{12}=\dfrac{x}{9}$

$\\ \sf\longmapsto 12x=8(9)$

$\\ \sf\longmapsto 12x=72$

$\\ \sf\longmapsto x=\dfrac{72}{12}$

$\\ \sf\longmapsto x=6$

Given that f(x)=2x/3 evaluate f^-1(6)

abruzzese [7]

Answer:

Step-by-step explanation:

we know by definition that

$f^{-1}(f(x))=x\\\\f^{-1}(\frac{2x}{3})=x\\\\f^{-1}(x)=ax\\\\f^{-1}(\frac{2x}{3})=a(\frac{2x}{3})=x\\\\f^{-1}(x)=\frac{3x}{2}$

so now we evaluate

$f^{-1}(6)=\frac{3*6}{2}\\\\=3*3\\\\f^{-1}(6)=9$

and if we want to do an extra step

$f^{-1}(f(6))=6\\\\f^{-1}(\frac{2*6}{3})=f^{-1}(4)=\frac{3*4}{2}=6$

which works.

mixas84 [53]

Answer:

According to Angle Bisector Theorem, if Ray YZ is an angle bisector, then MZ and NZ are congruent.

EH= 23. It is shown that ray FH bisects EFG, EF and EH are perpendicular, FG and HG are perpendicular. Then EH and GH are congruent. Therefore since GH= 23, then EH= 23
