To solve this system of equations by addition (elimination), what could you multiply each equation by to cancel out the x-variable? a: 2x−3y=−6b: −5x−9y=15 a. multiply a by 2 and b by 5 b. multiply a by -5 and b by 2 c. multiply a by 5 and b by -2 d. multiply a by 5 and b by 2

An equation representing lyle’s hedge-trimming business is a = 12n - 300 where a is the amount of profit or loss in dollars and n is the number of hedges trimmed. how would the graph of lyle’s business change if the equation a = 10n - 300 represented his business? the graph would be flatter. the graph would be steeper. the graph would start closer to the origin. the graph would start lower on the y-axis.

The sum of the reciprocal of a positive number and the reciprocal of 2 more than the number is 3/4 equation: the number is
