Pls help I really need it ! On a mathematics test, all correct multiple choice questions are worth 4 points, and all correct true/false questions are worth 2 points. Monica earned a total of 46 points from all of her correctly answered questions. In addition, she answered a total of 13 questions correctly of both multiple choice and true/false combined. Let x = correct multiple choice, let y correct true/false, and let this system of equations represent

the situation: x+y+13

a. Identify the constraints. Explain what they mean. Use complete sentences.
b. Determine if a solution exists. If so, identify it. Here is a graph of the system.

he kicked it up? is this the answer ?

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.
