Identify geometric figures

3 Answers are:choice 2, ray CAchoice 4, circle Cchoice 6, angle BCE

Explanation:

choice 1 is not valid because CA is actually a ray, not a line segmentchoice 2 is valid as we definitely have a ray starting at C and extending toward A forever.choice 3 is not valid. Angle ABC is not drawn fully. We don't have a line, segment or ray connecting points A and B. In contrast, angle ACB is drawn. Choice 4 is valid because this says "circle C". A circle can be named simply by its center alone. Choice 5 is not valid because we don't have a ray directly connecting B to EChoice 6 is valid because it is shown in the diagram as one of the central angles of the circle. This angle exists because we have lines connecting C to B, and also C to E, with C as the vertex of the angle.Choice 7 is not valid because we don't have a single line directly connecting A and E.

x = -

Step-by-step explanation:

- 4x + = - 9x +

Multiply through by 6 ( the LCM of 3, 2 and 6 ) to clear the fractions

4 - 24x + 21 = - 54x + 5 , that is

25 - 24x = - 54x + 5 ( add 54x to both sides )

25 + 30x = 5 ( subtract 25 from both sides )

30x = - 20 ( divide both sides by 30 )

x = = -
