F is the midpoint of EG If EF = x + 2 and FG = 2x - 6, find<br> FG
mezya [45]

Answer:

FG = 10

Step-by-step explanation:

EF = x + 2 ; FG = 2x - 6

F is the mid-point of EG. So, EF = FG

=  > x + 2 = 2x - 6

=  > 2x - x = 6 + 2

=  > x = 8

FG = 2×8 - 6 = 10

G(g(x)) g=(x+14)/(x+2)
GalinKa [24]

\bf g(x)=\cfrac{x+14}{x+2}~\hspace{8em}g(~~g(x)~~)=\cfrac{g(x)+14}{g(x)+2}\\\\\\(~~g(x)~~)=\cfrac{~~\frac{x+14}{x+2}+14~~}{\frac{x+14}{x+2}+2}\implies (~~g(x)~~)=\cfrac{~~\frac{x+14~~+14x+28}{x+2}~~}{\frac{x+14~~+2x+4}{x+2}}\\\\\\(~~g(x)~~)=\cfrac{~~\frac{15x+42}{x+2}~~}{\frac{3x+18}{x+2}}\implies (~~g(x)~~)=\cfrac{15x+42}{\underline{x+2}}\cdot \cfrac{\underline{x+2}}{3x+18}\\\\\\(~~g(x)~~)=\cfrac{15x+42}{3x+18}\implies (~~g(x)~~)=\cfrac{3(5x+14)}{3(x+6)}\implies (~~g(x)~~)=\cfrac{5x+14}{x+6}

What is the y-intercept of the function f(x) = –f(x) equals negative StartFraction 2 Over 9 EndFraction x plus StartFraction 1 O
lora16 [44]

Answer: Third option

Step-by-step explanation:

The equation of the line in Slope-Intercept form is:

y=mx+b

Where "m" is the slope of the line and "b" is the y-intercept.

Given the function f(x):

f(x)=-\frac{2}{9}x+\frac{1}{3}

Since f(x)=y, you can rewrite it:

y=-\frac{2}{9}x+\frac{1}{3}

You can identify that:

m=-\frac{2}{9}\\\\b=\frac{1}{3}

Therefore, you can determine that the y-intercept of the given function is:

b=\frac{1}{3}

Observe that this matches with the third option.
