O 5 feet
O 100 feet
O 50 feet

Determine the difference: 3.2 × 1010 – 1.1 × 1010. write your answer in scientific notation.

What are the solutions of the system? solve by graphing. y = -x^2 -6x - 7 y = 2

Which statements describe the solutions to the inequality x< -20 check all that apply. there are infinite solutions. each solution is negative. each solution is positive. the solutions are both positive and negative. the solutions contain only integer values. the solutions contain rational number values.
