Answer:
Mine was multiple choice and I got c
Step-by-step explanation:
What 2 numbers multiply to get -20 and add to get -8
-10 and 2
(p-10)(p+2)
If you simplified a two-equation system and all variables were eliminated, two outcomes are possible.
If the final equation is a true equation, like 3=3, then the system has an <em>infinite number of solutions </em> (the equations graph the same line, and all points appear on both graphs)
If the final solution is a mathematically false equation, like 0=-8, the system has no solution. The lines are parallel and never intersect (have a solution)
so namely, the "common difference" d = -4, and the first term a₁ = 7.
