Which is the graph of linear inequality 2y > x – 2?
DanielleElmas [232]

On a coordinate plane, a dashed straight line has a positive slope and goes through (negative 4, negative 3), (0, negative 1), and (2, 0). Everything to the left of the line is shaded.

<h3>How to graph inequality?</h3>

Inequality of a graph is represented with the greater then(<), less then(>) or with the other inequity signs. The inequality line on the graph is represented with the dotted lines.

The given linear inequality is,

2y > x - 2

Solve it further,

2y > x - 2\\2y-x > - 2

Change the inequality with changing the sign of it,

x-2y < 2

The inequality equation is graphed, which can be shown in the image provided below. In this graphed equation,

  • The inequality is shaded with dotted line.
  • As the equation is linear. Thus, in the graph, a straight line is plotted.
  • The sign in of greater than. Thus, the left of the line is shaded.

Thus, on a coordinate plane, a dashed straight line has a positive slope and goes through (negative 4, negative 3), (0, negative 1), and (2, 0). Everything to the left of the line is shaded.

Leya [2.2K]

Answer:

4.  m_LON + m_MON = m_LON; m_JKL + m_IKH = m_HKJ

Step-by-step explanation:

Both interior angles of each add up to m_LON:m_HKJ

To prove this we show the interior angles add + sign to each prove LON angle, and : colon separates from the proof of m_JKL+m_IKH= m_HKJ.

A family of right triangles has side lengths in the approximate ratio 3:4:5. One right angle
velikii [3]

Answer:

2,016.67 sq. cm

Step-by-step explanation:

Given the approximate ratio of the sides of a rectangle as 3:4:5.

Total ratio = 3+4+5 = 12

Area of the rectangle = 1/2*base *height

get the base;

base = 3/12 * 220

Base =  55cm

Get the height

Height = 4/12 * 220

Height = 880/12

Height = 73.3cm

Area = 1/2 * 55 * 73.3

Area = 2,016.67 sq. cm

Prove: If a chord of a circle makes an angle of 30° with a diameter, prove that the distance from the center to the chord is one
Svet_ta [14]

Answer:

See explanation.

Step-by-step explanation:

Let BC be the diameter of the circle with center at point O, AB be the chord and ∠ABC=30°. OD is the distance from the center to the chord.

Consider triangle BDO. This triangle is special 30°-60°-90° right triangle. The leg OD is opposite to the angle of 30° and is half of the hypotenuse. The hypotenuse of the triangle BDO is BO. BO is the radius of the circle and is equal to half of the diameter AB. Thus,

OD=\dfrac{1}{2}BO=\dfrac{1}{2}\cdot \dfrac{1}{2}AB=\dfrac{1}{4}AB.
