1 is the only number they all have in common
Answer:
Domain: x
0 or [0,infinity)
Step-by-step explanation:
f(x)= 
and g(x)=3-x
We are told to multiply the two functions so we multiply:
(fg)(x)=*(3-x)
(fg)(x)=3-x
Now this is a square root function and it can only go to the right because the square roots of numbers less than 0 are imaginary numbers. Therefore the domain must be greater than or equal to 0.
Answer:
1: -7x +4x -11=22 Answer: <em> </em>x=−11
2: 3x - 5 = 7 Answer: x=4
3: 3(x + 7) = 5x
-7 Answer: x=14
4: 2(x-5) + 3x =20 Answer: x=6
Step-by-step explanation
1: <em> </em>x=−11
2: x=4
3: x=14
4: x=6
Above is the answers.
Down is the steps of the questions.
Example for question 1
1: Step 1: Simplify both sides of the equation.
2: Step 2: Add 11 to both sides.
