1.) Bobby has $150 in his account and saves $100 per week. Erick has $350 in his account and saves $50 a week. Choose the equation that you would use to find out how many weeks it would take for them to have the same amount in each account. * A.) 150 + 100x + 50 = 350
B.) 100x + 150 = 50x + 350
C.) 150 + 350 = 50x + 100x
D.) 100 + 150x = 50 +350x

2.) While at the music store, Drew bought 5 CDs, all at the same price. The tax on his purchase was $6, and the total was $61. Write and solve an equation to determine the price of each CD? *

B.) $11.00
C.) $11.20
D.) $12.20

the answer is mp

step-by-step explanation:

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.
