Hey, here are all the problems. Im not sure how to do this and my teacher isnt giving me much time. Help would be apricated

Anton [14]

Answer:

Step-by-step explanation:

9x+8x+5+11= 17x+16

-5x-2x-7+6= -7x-1

-x-5x-9-4= -6x-13

3x-x-4+7= 2x+3

7x-5x+4-5= 2x-1

2x+7x-3+11= 9x+8

-4x+6x-5-8= 2x-13

12x-2x-14-3= 10x-17

5x-5x+4-12= -8

Hope this helps (brainliest is appriciated)

If f(x)=4x+3 and g(x)= the square root of x-9, which is true? 2 is in the domain of f of g or 2 is not in the domain of f of g?

andreev551 [17]

Answer:

2 is not in the domain of f of g

Step-by-step explanation:

* Lets revise at first the meaning of f of g (composite function)

- A composite function is a function that depends on another function

- A composite function is created when one function is substituted into

another function

- Example:

# f(g(x)) is the composite function that is formed when g(x) is

substituted for x in f(x).

- In the composition (f ο g)(x), the domain of f becomes g(x)

* Now lets solve the problem

∵ f(x) = 4x + 3

∵ g(x) = √(x - 9)

- Lets find f(g(x)), by replacing x in f by g(x)

∴ f(g(x)) = f(√(x - 9)) = 4[√(x - 9)] + 3

∴ f(g(x)) = 4√(x - 9) + 3

∵ The domain of f is g(x)

- The domain of the function is the values of x which make the

function defined

∵ There is no square root for negative values

∴ x - 9 must be greater than or equal zero

∵ x - 9 ≥ 0 ⇒ add 9 for both sides

∴ x ≥ 9

∴ The domain of f of g is all the real numbers greater than or equal 9

∴ The domain = {x I x ≥ 9}

∵ 2 is smaller than 9

∴ 2 is not in the domain of f of g

Which of the following illustrates the truth value of the given conditional statement? p: 2 + 2 = 4 q: 7 + 1 = 7 T F → F T T → T

musickatia [10]

Answer:

T F → F is the correct answer.

Step-by-step explanation:

In the given question if p illustrates p: 2 + 2 = 4

which is true so the truth value of this statement p is True.

Now the other statement q illustrates q: 7 + 1 = 7

Which is a false statement so the truth value of this statement is False.

As we know when "p→q ( p implication q), the truth value of implication is False only when truth value of p is True and for statement q the truth value is False."

We can see from the truth table truth value of p→q will be False.

So T F → F
