Which number line shows point A at 3, point B at −1.5, point C at , and point D, which is the opposite of point A?

Oduvanchick [21]

Step-by-step explanation:

We have that point A is at 3.

This is 3 units to the right of 0 on the number line.

The point that is opposite of A should be 3 units to the left of 0.

That point will be at -3.

Therefore you have to choose the point that is on -3.

It should be similar to one in the attachment.

The question is:

saul85 [17]

$f(x) = \sqrt{x+1} \\ y = \sqrt{x+1} \ or \ y^2 = x+1 \ or \ x = y^2 - 1 \\ Therefore, \ f^{-1}(x)=x^2 - 1$

$(fof^{-1})(a) = f(f^{-1}(a))=f(a^2-1) \\ =\sqrt{a^2-1+1}=\sqrt{a^2}=a \\ \\ (f^{-1}of)(a)=f^{-1}(f(a))=f^{-1}(\sqrt{a+1})= \\ (\sqrt{a+1})^2-1 = a+1-1 = a$

Therefore, $(fof^{-1})(a) = (f^{-1}of)(a) = a$

A radio talk show host asks listeners to call the radio station and give their opinions on a proposed new city ordinance. He use

vladimir1956 [14]

I would say that the best answer is actually that people who are not opposed to the new rule are less motivated to call than the people who are opposing it, who feel that they need to do something about it.

But this is not one of the options. Among the options, the best is:
A. The survey is voluntary and includes only listeners of this radio program.
