- The equation of this line is x=3.

- And I think it's also, This graph is a function of whose range is set at {3}.

Answer:

D. The equation of this line is x=3

E. This graph is not a function because the value x=3 is assigned to mre than one y-value.

Step-by-step explanation:

The range is all real numbers.

The domain of this graph is x=3, but it is not a function

The graph is a vertical line whose equation is x=3 because the graph passes through (3,y).

This graph cannot represent a function because it will not pass the vertical line test.

In other words, the x-value of 3 is assigned to more than one y-value.

Therefore the correct answers are:

Option D and E

What is sin -1(1/2) if the terminal side of 0 is located in quadrant 1.
kotykmax [81]

Answer:

30

Step-by-step explanation:

\sin^{-1}(\theta) is going to output a number in between \frac{-\pi}{2} and \frac{\pi}{2}.

Luckily you are looking for \theta in the 1st quadrant which is contained in the given interval above, so the answer just comes down to what the calculator returns from entering \sin^{-1}(\frac{1}{2}) in your calculator.

You may also use the unit circle.  sine value refers to the y-coordinate on there.

So you are looking for when the y-coordinate is 1/2 in the fist quadrant which is at 30 degrees.

Use the linear combination method to solve the system of equations PLZ HELP I WILL GIVE BRAINLIEST AND ITS WORTH A LOT OF POINTS
jasenka [17]
2x-3y=13...(1)
2x+4y=-8...(2)

Multiply equation 2 by -1 to eliminate x

2x-3y=13
+ -2x-4y=8
—————
-7y=21
y=-3
Substitute y=-3 into equation 2
2x+4(-3)=-8
x=2

Therefore, the solution to the system is (2, -3)
