Answer:
6
Step-by-step explanation:
3( 4x - 6)
Let x =2
3( 4*2 -6)
3(8-6)
3*2
6
Check
12x-18
12*2 -18
24-18
6
Both equal 6
Answer:
B
Step-by-step explanation:
x-5+3x-5+90=180 you set it up this way because you need to find what x is equal to and by adding those two equations plus 90 then setting the against 180 you can find x because all three angles in a triagnle add up to 180.
x-5+3x-5+90=180
4x-10+90=180 you combined like numbers
4x+80=180 combined like numbers
-80 -80 subtract 80 from both sides because you are trying to--- get x alone
4x=100 now to get x alone you have to divide 4 from both ---- sides
/4 /4

The domain of a function f(x)/m(x) = 1/√x(x² - 4) is (0, ∞) - {0, 2, -2} for other function is shown in the solution.
<h3>What is a function?</h3>
It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have:
f(x) = 1/√x
m(x) = x² - 4
Domain of f(x)/m(x):
f(x)/m(x) = (1/√x)/(x² - 4)
f(x)/m(x) = 1/√x(x² - 4)
The denominator cannot be zero:
√x(x² - 4) ≠ 0
x(x - 2)(x+2) ≠ 0
x ≠ 0, 2, -2
and x > 0
Domain of f(x)/m(x) is: (0, ∞) - {0, 2, -2} or 
Domain of f(m(x)):
f(m(x)) = 1/√(x² - 4)
x² - 4 > 0
Domain: 
Domain of m(f(x)):
= ((1/√x)² - 4)
Domain: 
Thus, the domain of a function f(x)/m(x) = 1/√x(x² - 4) is (0, ∞) - {0, 2, -2} for other function is shown in the solution.
