The small triangle is 1/2 the size of the larger one ( comparing like sides 5 is 1/2 of 10).

This means AC is 1/2LN.

So you have:

x +5 = 1/2(3x +3)

Simplify:

x+5 = 1.5x +1.5

Subtract 1.5x from each side:

-.5x +5 = 1.5

Subtract 5 from each side:

-.5x = -3.5

Divide both sides by -.5:

x = -3.5 / -.5

x = 7

Now you have x.

AC = x +5 = 7+5 = 12

The answer is G.

If (fx)=5x, what is f^-1(x)
zysi [14]

Answer:

x/5

Step-by-step explanation:

To get the inverse function you need to leave the x alone and then switch variables ( f(x) = y)

f(x) = 5x

y = 5x

y/5 = x

Now that x is alone you switch the x for y and the y for x and you get:

x/5 = y

And this new y is the inverse function of f(x) ( f^-1(x))

f^-1(x) = x/5

Substitute each value of x in y=2x-3

so,

first box (-2)
y= 2(-2)-3
y= -4-3
y= -7

second box (0)
y= 2(0)-3
y= 0-3
y= -3

third box (3)
y=2(3)-3
y=6-3
y=3

это проблема LCM, поэтому вот как ее решить.

Том звучит через 9, 18, 27, 36 минут после первоначального звучания.

Звуки Эми в 12, 24, 36 минут
