Marlene went to Marcy's and bought a dress for a birthday party. She fell in love with a red one that had a 20% discount. Her mom said she could pay the taxes only if the total of the dress was less than $150.oo. If the price of the dress before mark off was $185.00, would Marlene be able to buy the dress she wants? Explain

with btw u said 100pts but it clearly says

i answerd and just got 10pts

no hate

x = 3 ± √(5+y)

1. when "a" is a root of a polynomial, (x -a) is a factor of it. for the three roots given, the factors of the desired polynomial are (x +2)(x -1/2)(x -3).

in order to make the leading coefficient be negative, we need to multiply this product by a negative number. any negative number will do, but we choose a small (magnitude) value that will eliminate the fraction: -2.

then

f(x) = -2(x +2)(x -1/2)(x -3) = -(x +2)(2x -1)(x -3)

= -(2x² +3x -2)(x -3)

= -(2x³ -3x² -11x +6)

f(x) = -2x³ +3x² +11x -6

2. a graph created by the desmos on-line graphing calculator is shown, and the zeros are highlighted.

3. as indicated in part 1, the multiplier of this equation can be anything and the zeros will remain the same. you want a negative leading coefficient, so the "anything" is restricted to any of the infinite number of numbers that will make that be the case.
