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:
15 minutes i think
Step-by-step explanation:
45÷6=7.5
meaning 7.5 minutes per girl
so 4 girls would be 30 minutes of work
so 45-30=15

Answer:
3.162278
Step-by-step explanation:
√10= 3.16227766
then find the millionths place which is 3.16227766
then you round that number based on the number to the right of it which is a 6 so you round it up
so the answer is 3.162278
