Hurrygiven the quadratic equation y=5(x-2)^2+4, state the following parts: vertex, is the parabola opening up or down? , the axis of symmetry

Multiplying an even number of negative numbers gives an answer that is choose from:

Lance lived in portugal and brazil for a total of 14 months to learn portuguese. he learned an average of 130 new words per month when he lived in portugal, and an average of 150 new words per month when he lived in brazil. in total he learned 1920 new words. write a system of equations to represent the situation. use x to represent portugal, and y to represent brazil

The vertex of this parabola is at (-2,-3). when the x-value is -1, the y-value is -5. what is the coefficient of the squared expression in the parabola's equation?
