Answer: (5, -7)
Step-by-step explanation:
On a graph, the solution(s) of two equations is/are the points at which they intersect.
For the graph shown, there is only one intersection point, (5, -7). This set of coordinates satisfies both equations, so it is a solution to the system.
Well.....2.82 divided by 1 = 2.82
The formula for C(n,r), also known as "n choose r" or a combination,
is:
nCr = n! / (r!(n-r)!),
where n is the total number of options and r is number you must choose
The number generated is the total number of possible combinations.
The ! means factorial. For example, 4! = 4 x 3 x 2 x 1
