Does this system of equations have one solution, no solutions, or an infinite number of solutions? 2x + 3y = 64x + 6y = 12

Evaluate cos2θ for cosθ = square root of 3/2

If the line in the graph is shifted up two units which is the equation of the new line

Which situation could best be represented by this linear equation? 24x + 38y = 520 > if x represents the number of bracelets and y represents the number of rings, there were 24 more bracelets sold than rings. the total sales were $520. if x represents the number of bracelets and y represents the number of rings, there were 38 more bracelets sold than rings. the total sales were $520. if x represents the number of bracelets sold at $24 each and y represents the number of rings sold at $38 each, the total sales were $520 if x represents the number of bracelets and y represents the number of rings, there were 520 bracelets and rings sold. bracelets were $24, and rings were $38. e
