Question 384882: i need to plot the graphs of equations and use the X and Y intercept method, and a check point. Using the X value when solving for the chechpoint.
4x-3y=12
checkpoint is: 1
i got for the x intercept (3,0)
i got for the y intercept (0, -4)
but i am having troubles with the checkpoint (1,?)

Question 388174:  Figure is similar. Points A, B, C, D, E, F. AB=DE, BC=CD=EF. AB does not equal BC.
"Give the postulate(s), definition(s), properties, or previous statement(s) that make each statement about the diagram true."
8.CE=AC
10. Line segment CE is congruent to line segment DF
(Sorry I'm putting 2 problems here, but they go to the same figure)

Question 390952: We are learning about The Triangle Inequality and I am stuck on a question:
If the sides of a triangle have the following lengths, find all possible values of x.
AB=2x+5, BC=3x-2, AC=4x-8
(The answer the book has is X > 3, but I am not sure how)
Thanks.
