Considering High School level question, answer can be written as:
A system of 2 linear equations is [two] dimensional. It is a graph of [two] lines. The solutions can be [unique] solution if the graph intersects. [No] solution if the lines are parallel - meaning they have the same slope, or [Infinitely many] solutions if they are the same line.
Explanation:
when two lines are drawn on a two-dimensional plane then there are only three possible cases:
Case1: lines will intersect
In that case you will get a unique solution at the intersection point.
Case2: lines are parallel but don't touch each other
In that case there will be no point which lies on both lines so No solution.
Case3: lines are overlapping.
In that case all the points lies on both lines so infinitely many solutions.
To find total combinations, multiply the quantity of each part by each other.
9 x 6 x 10=540 total
320 / 80 equals 4 so times 2 by 4 so it will take 8 hours
<span>D = 4 - 4*9*(-7) = 4 + 252 = 256 = 16*16
x1 = (-2 + 16)/9 = 14/ 9
x2 = (-2 - 16) / 9 = -2

Hey there Nc085601pmzc,
Answer:
Perimeter = Length + Breadth + Length + Breadth
= 50 + 25 + 50 + 25
= 150 cm
Hope this helps :D
