(f o g o h)(x) = f { g [ h(x) ] }

Which means: apply first function h, then apply function g to the result, and finally apply  function f to the new result.

h(25) = √25 = 5

g(5) = 5  - 3 = 2

f(2) = 3(2) = 6.

Answer: 6

How many solutions are there for 4x>8
Anni [7]

Answer:

\Huge \boxed{X>2}

Step-by-step explanation:

\large \textnormal{To solve this problem, first you have to isolate it on one side of the equation.}

First, divide by 4 from both sides.

\displaystyle \frac{4x}{4}=\frac{8}{4}

Solve.

\displaystyle 8\div4=\boxed{2}

Therefore, the solutions of 4x>8 is 2.

In conclusion, the correct answer is x=2.

A piano has 52 white keys. Write and use an equation to find the number of octaves on a piano keyboard.
Firdavs [7]
There are 7 keys in each octave (C,D,E,F,G,A and B) so it would make sense to divide 52 to 7.
52/7=7 octaves and 3 extra kets

Solve for 2:<br> 7x + 156°<br> 9x + 184°
Natalija [7]

Answer:

x = -14

Step-by-step explanation:

Simplifying

7x + 156 = 9x + 184

Reorder the terms:

156 + 7x = 9x + 184

Reorder the terms:

156 + 7x = 184 + 9x

Solving

156 + 7x = 184 + 9x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-9x' to each side of the equation.

156 + 7x + -9x = 184 + 9x + -9x

Combine like terms: 7x + -9x = -2x

156 + -2x = 184 + 9x + -9x

Combine like terms: 9x + -9x = 0

156 + -2x = 184 + 0

156 + -2x = 184

Add '-156' to each side of the equation.

156 + -156 + -2x = 184 + -156

Combine like terms: 156 + -156 = 0

0 + -2x = 184 + -156

-2x = 184 + -156

Combine like terms: 184 + -156 = 28

-2x = 28

Divide each side by '-2'.

x = -14

Simplifying

x = -14
