A line segment is drawn from (+6, +4) to (+9, +4) on a coordinate grid.Which explains one way that the length of this line segment can be determined?

A.
Add 9 + 6.

B.
Add 6 + 6.

C.
Subtract 9 – 6.

D.
Subtract 6 – 6.

Answers

Answer 1
Answer: Letter c. add 9-6 explains one way that the length of this line segment can be determined. In order to verify this for yourself, you can plot these two point on a Cartesian coordinate plane and manually measure the length of the line. Mathematically, the length of a line may be calculated by the distance formula given as: sqrt[(x2-x1)^2+(y2-y1)^2]

(-4,7),(-6,-4) find slope

Answers

To find the slope, plug the two coordinate pairs into the formula
m = (y_2 - y_1)/(x_2 - x_1). M will represent the slope.

M = (y_2 - y_1)/(x_2 - x_1)   Substitute in the x and y values
M = ((-4) - 7)/((-6) - (-4))   Subtract
M = (-11)/(-2)   Simplify
M = (11)/(2)

The slope is (11)/(2)

Step-by-step explanation:

Which is the angle measure represented by 7.5 rotations clockwise?

Answers

Answer:

-2700°


Step-by-step explanation:

  • 1 rotation is 360°, also
  • Counterclockwise angles are POSITIVE ANGLES & Clockwise angles are NEGATIVE ANGLES

7.5 rotations is 360*7.5=2700 degrees

and since it is clockwise, the angle is negative.


Hence, 7.5 rotations clockwise means -2700°
1 rotation equals 360 degrees.  1/2 of a rotation equals 360/2 = 180 degrees.  So, 7 times 360 degrees = 2520 degrees plus 180 degrees = 2700 degrees.

CD HI MN RS what letters are next?

Answers

Answer:

WX

Step-by-step explanation:

CD HI MN RS we have to find next letters.

To find next letters first we write alphabets to find the relation in this sequence.

A B C D E J G H I J K L M N O P Q R S T U V W X Y Z

As we can see after 3 letters two letters have been taken.

so to continue the sequence next letters would be WX,
I think your answer is WX. The pattern from what I can tell is: ab CD efg HI jkl MN opq RS tuv WX yz.

How to expand and simplify (2x+3y)(x-y)

Answers

(2*x+3*y)*(x-y) this is expanded form
Multiply (2x)(x-y). Then Multiply (3x)(x-y). After that, you have to add the two. If you want it to be simplified, add the x together, and then add the y together. :)
