Use matrix manipulation to solve for a, b, and c. set up a matrix equation for ax = b based on the system of equations you derived in part b where x is a matrix of the variables a, b, and c. then, use gauss-jordan elimination to find the inverse of a. finally, use your results to write the equation of the parabola. show your work and final equation in the space provided.

answer: the answer is one of

step-by-step explanation:   we are given to write a proper fraction where the whole is divided into an even number of equal parts less than ten, and an odd number of those parts exist.

an even number less than 10 may be one of 2, 4, 6 or 8. so, the whole may be one of these four evens.

now, an odd number of these parts must exist, so the numerator must be an odd number, one of 1, 3, 5 or 7. it cannot be 9 because then the fraction will become improper.

thus, our fraction may be one of the following

2nd one in the first row is correct
