1. 4x = 7(x - 3) GIVEN
4x = (7)(x) + (7)(-3)
2. 4x = 7x - 21 DISTRIBUTIVE PROPERTY
4x - 7x = 7x - 7x - 21
3. -3x = -21 SUBTRACTION PROPERTY OF EQUALITY
-3x : (-3) = -21 : (-3)
4. x = 7 DIVISION PROPERTY OF EQUALITY
Answer:
The expression which is equivalent to (k ° h)(x) is ⇒ 2nd answer
Step-by-step explanation:
* Lets explain the meaning of the composition of functions
- Composition of functions is when one function is inside of an another
function
# If g(x) and h(x) are two functions, then (g ° h)(x) means h(x) is inside
g(x) and (h ° g)(x) means g(x) is inside h(x)
* Now lets solve the problem
∵ h(x) = 5 + x
∵ k(x) = 1/x
- We need to find (k ° h)(x), that means put h(x) inside k(x)
* Lets replace the x of k by the h(x)
∵ k(x) =
∵ h(x) = 5 + x
- Replace the x of k by 5 + x
∴ k(5 + x) =
∴ The expression which is equivalent to (k ° h)(x) is
The answer is B 36 because the chance of you grabbing a white or black is 12/15 meaning if you pulled 15 marbles, most likely 12 of them are white or black. so, because 15 goes into 45 3 times, you multiply 12/15 by 3 getting 36/ 45 meaning you will mostly pull 26 black or white marbles.
By the transversal theorem, if segments on a transversal cut by parallel lines are equal, then similar segments cut by the same parallel lines on another transversal are also equal.
Therefore
JK=KL=LM=5
=>
JM=3*5=15
