Answer:

Step-by-step explanation:

M is in the middle between S and T we know 2x+6 has to be the same as 3x+3 if 3x is one more x then 2x then we do 6-3 that eqauls 3 so X=3 and 2*3=6 and 6+6= 12.

Hey there! :D

Answer:

$\huge\boxed{SM = 12}$

SM = 2x + 6

MT = 3x + 3

M is the midpoint of SM

Write an expression to represent the length of ST:

ST = SM + MT

ST = 2x + 6 + 3x + 3

Combine like terms:

ST = 5x + 9

Since ST = 2(SM), set up another equation:

5x + 9 = 2(2x + 6)

5x + 9 = 4x + 12

Isolate the "x" variable:

5x - 4x = 12 - 9

x = 3.

Substitute in this value of "x" into the equation for SM:

2(3) + 6 = 12.

The Pythagorean theorem formula for a triangle is A^2 + B^2 = C^2 where A and B are the sides and C is the hypotenuse.

The sides of the triangle shown are AB and BC and the hypotenuse is AC,

so the correct answer would be:

(AB)2 + (BC)2 = (AC)2, because 25 + 144 = 169

Write the inverse function for the function, ƒ(x) = 1/2x + 4. Then, find the value of ƒ -1(4). Type the answer exactly in this f

WINSTONCH [101]

We can get the inverse function by first setting f(x) = y, solving for x, and after that switching y and x. So, let's solve for x:
$f(x)= \frac{1}{2}x+4$
$y= \frac{1}{2}x+4$
$2(y-4)=x$
$2x-4=y=f (x)^{-1}$

Then, just plug in 4 for x, and solve:
$2(4)-4= f (x)^{-1}$
$4=f (x)^{-1}$

There you have your answer.

X+4//6x =1/x A. x = -2 B. x = 0, -2 C. x = 2 D. x = 0, 2

KIM [24]

Answer:

Step-by-step explanation:

hello :

x+4/6x =1/x means :6x²/6x +4/6x =6/6x

for : x≠0 6x²+4 = 6

6x² =2

x²= 1/3

x= √1/3 or x= -√1/3
