When solving a system of two linear equations algebraically, how can you tell if the system has exactly one solution? A. There will be one set of ordered pairs for each equation that make up the solution.

B. There will be exactly one value for x and one value for y that makes both equations true.

C. The algebraic process will result in a numerical statement that is always true.

D. The algebraic process will result in a numerical statement that is never true.

Write numerical coefficient of y² in the expression 2x² - 15xy – 7y²

Create a graph for the demand for starfish using the following data table: quantity/price of starfish quantity (x axis) of starfish in dozens price (y axis) of starfish per dozen 0 8 2 6 3 5 5 2 7 1 9 0 is the relationship between the price of starfish and the quantity demanded inverse or direct? why? how many dozens of starfish are demanded at a price of five? calculate the slope of the line between the prices of 6 (quantity of 2) and 1 (quantity of 7) per dozen. describe the line when there is a direct relationship between price and quantity.

Prove that (x-2)is factor of p (x)=2x³-3x²-17x+30
