Who was the first person to use the greek letter pi to represent the number pi in mathematics

Write a recursive sequence that represents the sequence defined by the following explicit formula:

Consider the system: y = 3x + 5 y = ax + b what values for a and b make the system inconsistent? what values for a and b make the system consistent and dependent? explain

Drag each expression to the correct location on the solution. not all expressions will be used. consider the polynomial 8x + 2x2 - 20x - 5. factor by grouping to write the polynomial in factored form.
