You have 7.60 to buy cantaloupes for a fruit salad recipe. cantaloupes cost 1.90 each. write and solve an inequality that represents the number of avocado you can buy
i'm not sure on c, sorry.
the standard form is: y = -3x² +18x -24.
given is y = -3(x-2)(x-4)
using foil method to expand the parentheses: -
y = -3(x-2)(x-4)
y = -3(x² -2x -4x +8)
combining like terms: -
y = -3(x² -6x +8)
distributing -3 to the terms inside parentheses: -
y = -3x² +18x -24.
hence, standard form is: y = -3x² +18x -24.
