Answer:

triangle STU and WEK are CONGRUENT

ST=WK SIDE OF A CONGRUENT TRAINGLE ARE EQUAL

2M=N.....1

SU=WE

3M+5=N+8

3M+5=2M+8

3M-2M=8-5

M=3

NOW

N=2M=2×3=6CM

TU=WK=N=6CM.

15 cm
N=2m so 3m=1.5n then we can plug in that to get 1.5n+5=n+8 to get the value of n then we do our magic and get n=6 n+9 is 15 and it’s the same length as TU

Solve for x in the diagram * 10 POINTS HELP*

Alex73 [517]

Answer:x+42+3x = 90

Combine like terms:

3x+x = 4x

42+4x = 90

Subtract 42 to both sides

90-42 = 48

Divide 4 by 48

48/4 = 12

X = 12

100% right

If f(x) and f^-4(x) are inverse functions of each other and f(x) = 2x+5, what is f^-1(x)?

miss Akunina [59]

For this case we must find the inverse of the following function:

$f (x) = 2x + 5$

Then, we follow the steps:

We change $f (x)$ by y:

$y = 2x + 5$

We exchange the variables:

$x = 2y + 5$

We clear the variable "y":

$x-5 = 2y\\y = \frac {x-5} {2}$

We change y for $f^{-1}(x):$

$f^{-1}(x) = \frac {x-5} {2}$

Answer:

$f^{-1}(x) = \frac {x-5} {2}$
