Unless you show a picture, its impossible to solve.
<h3>
Answer: A) intersecting</h3>
-----------------------------------------------
Work Shown:
Solve the first equation for y
x+y = ab
y = -x+ab
y = -1x + ab
slope = -1, y intercept = ab
-----------
Solve for y in the second equation
bx - y = a
bx - y - a = 0
bx-a = y
y = bx - a
Slope = b, y intercept = -a
-----------
The first equation has a slope of -1. The second equation has a slope of b.
Since b cannot equal -1, this means the two equations have different slopes. It is impossible for these two lines to be parallel, because parallel lines have equal slopes. The different slope values tell us the lines cross at exactly one point.
Answer:
It decreased by 61.5%

The first one I THINK is 21 and the second one I THINK is 20. I'm not sure though sorry if I'm wrong
33 represents how many people that were seen on the street at the time when writing the equation
