Read a scenario right and equation to model the scenario and then use the equation to solve the problem Your pipes in your home first and the final bill was $269 the plumbing material would cost $119 and a charge of for the plumbers laborers is $60 per hour right in equation to model the situation then solve the equation for the number of hours the plumber worked on your plumbing

Can anyone help me pls ! I’ll mark you as a brainliest.

step-by-step explanation:

mean or average is 40.6

6 and 24

step-by-step explanation:

6 x 4 = 24

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.
