Can someone help me the four options would be 34 degrees btw

Answer:

Angle NKQ is 68 Degrees.

Step-by-step explanation:

With this, consider the arc that Angle NPQ is making. It is making an arc of 112 degrees since the Angle is coming out from the radius of the circle.

Now, there is also the arc 248 degrees for the remainder of the circle that is not within this angle's reach.

Since Angle NKQ shares these arcs, we can use the equation:

Big Arc + Small Arc / 2

to get the measure of this angle

(248 - 112) / 2

With this, Angle NKQ is 68 degrees.

Again, look for repeated entries in the domain.  If present, the relation cannot be a function.  1 maps 6 to 1, 2, and 3; 2 maps 5 to -1 and 9; 3 maps 1 to -6 and 0; and only 4 has no double mapping.  Therefore 4 is a function and the answer.

Answer the question on the attachment
Nonamiya [84]

Answer:

The answer to your question is below

Step-by-step explanation:

Part A.

               -3x + 7y = 13

Solve the equation for "y"

               7y = 3x + 13

                y = \frac{3}{7} x + 13

Part B.

Two lines are parallel if their slopes are the same

Two lines are perpendicular if their slope are opposite reciprocals

Slope of the first line = \frac{3}{7}

Slope of the second line = \frac{3}{7}

Conclusion: the lines are parallel because their slopes are the same.

I need help on this question!??
Dafna11 [192]

Answer:

The only thing you will do is to plug the x in the equation.

x = -2 ---> f(x) = -6

x = 0 ---> f(x) = 0

x = 3 ---> f(x) = 9

x = 7 ---> f(x) = 21

f(x) = 3x

f(-2) = <u>3(-2)</u>

f(-2) = -6

f(0) = <u>3(0)</u>

f(0) = 0

f(3) = <u>3(3)</u>

f(3) = 9

21 = 3x

<u>21 / </u><u>3</u> = <u>3x / 3</u>

7 = x

Hope this helps, thank you :) !!
