Ken drew a pair of intersecting rays and marked a angle between them.
andre [41]

Answer:

Option 3 is the best option that compares the pair of intersecting rays with the angle

Step-by-step explanation:

The definition of angle says that an angle is a shape that is produced by the intersection of two rays that have a common end point.

A ray is a line segment that has only one end point and is extended infinitely in a unique direction

Please help me I need help please​
MakcuM [25]

Answer:

p = 4

Step-by-step explanation:

Given equation:

x^2+(p-3)y^2-4x+6y-16=0

<u>Standard equation of a circle:</u>

(x-a)^2+(y-b)^2=r^2

(where (a,b) is the centre of the circle, and r is the radius)

If you expand this equation, you will see that the coefficient of y^2 is always one.

Therefore, p-3=1

\implies p=1+3=4

<u>Additional information</u>

To rewrite the given equation in the standard form:

\implies x^2+y^2-4x+6y-16=0

\implies x^2-4x+y^2+6y=16

\implies (x-2)^2-4+(y+3)^2-9=16

\implies (x-2)^2+(y+3)^2=16+4+9

\implies (x-2)^2+(y+3)^2=29

So this is a circle with centre (2, -3) and radius √29

Tina completed 2/3 of her homework. George completed 7/8 of his homework. Who completed a greater fraction of homework
Amiraneli [1.4K]

get a common denominator of 24

2/3 * 8/8  vs 7/8 * 3/3

16/24 vs 21/24

16/24<21/24

2/3 <7/8

Need help solving this for two points for a graph...3x+3=0​
coldgirl [10]

3x + 3 = 0 //Subtract -3 on both sides

3x = -3 //Divide 3 on both sides

x = -1

Here x = -1 and y is all the values where x = -1, so basically from negative infinity to infinity.

Make sure when writing the solution, y is any value and x stays the same.

Solution: (-1,0) and (-1,1)

//Hope this helps
