How would you calculate 7x + 1=68 with only one variable? (Working please)

1 answer:

6 0

Well if you're solving for x this would be rather simple. 7x +1=68 , then you'd minus 1 from both sides. 7x = 67 then divide 67 by 7. The answer isn't a whole number so x would either be 67/7 or 9.57.. etc.

The domain of u(x) is the set of all real values except 0 and the domain of v(x) is the set of all real values except 2. What ar

Answer:

Third option

x ≠2 and x cannot be any value for which v(x) = 0

Step-by-step explanation:

In this problem we are asked to find the domain of the function

$(UoV)(x)$

We know that $(UoV)(x) = U(V(x))$ .

We know that:

Domain of U(x) is all real numbers except x = 0

Domain of V(x) is all real numbers except x = 2.

Then the domain of the composite function U(V (x)) is:

all real numbers except x = 2. (since x = 2 does not belong to the domain of V(x) and all values of x for which V(x) = 0 (since x = 0 does not belong to the domain of U(x))

Finally the domain of $(UoV)(x)$ ) is:

$x \neq 2$ and $V(x) \neq 0$
