What describes a rhombus???

If the ordered pair (a, b) satisfies the inequality. y > x-4, three of these statements are

Mumz [18]

Answer:

If you subtract 4 from a, it will be greater than b

Step-by-step explanation:

Ok, so in order to solve this, it would be easier to substitute (a,b) into the equation:

b>a-4

Ok, next, you just have to work out each individual question to see which one is incorrect. You can immediately know it is the first one, and this is because we know that B is larger in this equation, but the problem says that subtracting 4 from a would be greater than b. This is incorrect, b is greater than 4-a, so the top left would be your answer.

Hope this helps!

On a coordinates plane, a line passes through ( - 2 , 3 ) and ( 2 , 6 ). Which of the followings lies on the same line.

Dahasolnce [82]

By direct comparison and definition of line segment we notice that the point (x, y) = (- 6, 0) lies on the line segment AB as each AP is a multiple of former. (Correct choice: C)

<h3>What point lies on a line segment?</h3>

According to linear algebra, a point lies in a line segment if its vector is a multiple of the vector that generates the line segment itself, that is:

AB = k · AP (1)

The vector that generates the line segment is:

AB = (2, 6) - (- 2, 3)

AB = (4, 3)

And the vectors related to each point are:

Case A

AP = (- 2, 12) - (- 2, 3)

AP = (0, 9)

Case B

AP = (6, 12) - (- 2, 3)

AP = (8, 9)

Case C

AP = (- 6, 0) - (- 2, 3)

AP = (- 4, - 3)

Case D

AP = (- 6, 6) - (- 2, 3)

AP = (- 4, 3)

By direct comparison and definition of line segment we notice that the point (x, y) = (- 6, 0) lies on the line segment AB as each AP is a multiple of former. (Correct choice: C)

Which figures can be precisely defined by using only undefined terms? Check all that apply.

anyanavicka [17]

Undefined terms are formed using known words or terms to describe a new word. The three undefined terms are point, line and plane. These 3 terms are the building blocks of geometry. They are explained but not defined unlike other terms. Hope this helps.

Helppp me pleaseeeeeee

MAXImum [283]

Circumference = πD

π*49 = 153.94 (We can leave it as it is because there are two halves to the circle on either side of the training track)

81*2 = 162 (There are two 81 meter lines)

153.94+162 = 315.94m

The length of the training track is 315.94m

Hope this helps! :)
