The slope of a line parallel to this line is -4/7
And the slope of a line perpendicular is 3/4
Answer:
(a.) On line 4, Travis subtracted $188 from $180 and got a positive answer. The difference should be -$8.00.
(b.) <em>(work provided in picture)</em> To get his account back to 0, Travis needs to deposit $21.80 or more to avoid another overdraft fee.
Right triangles add up to 180 degrees and one of the angles is 90
4×4=16 (4^2)
16×4=64 (4^3)
64×4=256 (4^4)
So 256 is 4^4
