Ok. so remember that 1 lb = $10. if you have 2.5 lbs, how much money would you pay?

There is a line with slope 1/a going through the point (a, a²). find the equation of the line perpendicular to this line at this point. (don’t let this problem intimidate you! solve the problem as you would if i’d given you specific values. just use variables instead.)

Which ordered pair is a solution to the system of linear equations? 2x + 3y= 6 –3x + 5y = 10

Solve each quadratic equation by factoring and using the zero product property. [tex]x^2+6x+8=0[/tex]
