A. Find an equation of the line perpendicular to the graph of 4x-2y = 9 that passes through the point at (4, 6).
-
y = -x + 8

dy = 2x + 8
b.

Refer to interactive solution 17.45 to review a method by which this problem can be solved. the fundamental frequencies of two air columns are the same. column a is open at both ends, while column b is open at only one end. the length of column a is 0.504 m. what is the length of column b?

What’s the range cuz i can’t find it?

Square a has a side length of (2x-7) and square b has a side length of (-4x+18). how much bigger is the perimeter of square b than square a?and show all work! you so
