Answer:

Draw a point one unit to the left of zero.

Step-by-step explanation:

The equation of unknown w is given here and we have to solve it and then we have to check how to draw the point w on the number line.

Now, the equation is - 5w + 9 = 14

⇒ - 5w = 5

⇒ w = - 1

Now, we know that in a number line if we move right from zero then this is a positive direction and if we move left from zero then this direction is the negative direction.

Hence, to plot w = - 1, we must draw a point one unit to the left of zero. (Answer)

What is the inverse of y=pi/2+sin x

Alekssandra [29.7K]

Answer:

$f^{-1}(x)=\sin ^{-1}(x-\frac{\pi}{2})$

Step-by-step explanation:

The given function is

$y=\frac{\pi}{2}+\sin x$

To find the inverse of this function, we interchange x and y.

$x=\frac{\pi}{2}+\sin y$

we now solve for y.

$x-\frac{\pi}{2}=\sin y$

Take the sine inverse of both sides to obtain;

$\sin ^{-1}(x-\frac{\pi}{2})=y$

Hence the inverse of the given function is;

$f^{-1}(x)=\sin ^{-1}(x-\frac{\pi}{2})$

where $\frac{\pi}{2}-1\le x\le \frac{\pi}{2}+1$

Which mathematical property is demonstrated?

RSB [31]

Answer:

The commutative property states that you can rearrange the order of the numbers and get the same result. The commutative property states that you can rearrange the order of the numbers and get the same result. The addition properties are the exact same, but replace multiply with add. Your answer is D.

Step-by-step explanation:

All the problem is doing is switching the numbers to different sides of the equation. You will still get the same answer.
