Tell whether x=6 is a solution of x−1 ≤ 7.

MrRa [10]

Answer:

x = 6 is a solution of x - 1 $\leq$ 7.

Step-by-step explanation:

First, plug in x = 6 into the inequality.

x - 1 $\leq$ 7 for x = 6

6 - 1 $\leq$ 7

Now, solve.

6 - 1 = 5

5 $\leq$ 7

The statement above is true, so x = 6 is a solution to x - 1 $\leq$ 7.

Please inform me of any mistakes.

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

Liula [17]

Answer: the restrictions on the domain of (u°v) (x) are x ≠ 2 and which v(x) ≠ 0.

Justification:

1) the function (u ° v) (x) is u [ v(x) ], this is, you have to apply first the function v(x) whose argument is (x), and later the function u (v(x) ) whose argument is v(x).

2) So, the domain of the composed function (u ° v) (x) has to take into account the values for which both functions are defined.

3) The domain excludes x = 2 because v(x) is not defined for x = 2.

4) And the domain must also exclude v(x) = 0 because u is not defined for v(x) = 0.

5) So, in conclusion, the domain is all the real values except x = 2 and the x for which v(x) = 0.

Therefore the resctrictions are x ≠ 2 and v(x) ≠ 0
