Find the coordinates of a point P that lies on the directed segment from C(-9, -3) to D(8,5) and partitions the segment in the ratio 1 to 4.
If you get this please help :) Thank you

The border line of the linear inequality 4x + 7y < 5 is dotted true or false?

Girardo is using the model below to solve the equation . girardo uses the following steps: step 1 add 4 negative x-tiles to both sides step 2 add 1 negative unit tile to both sides step 3 the solution is which step could be adjusted so that gerardo's final step results in a positive x-value? in step 1, he should have added 4 positive x-tiles to both sides. in step 1, he should have added 3 negative x-tiles to both sides. in step 2, he should have added 4 negative unit tiles to both sides. in step 2, he should have added 1 positive unit tile to both sides.

Ab and bc form a right angle at point b. if a= (-3,-1) and b= (4,4) what is the equation of bc?
