Ithought of a number, added 4 5/7 to it, and got the number equal to the original one times 12. what was the original number?

Me asap! what is the slope of this line? enter your answer in the box.

Which of these statements is correct? the system of linear equations 6x - 5y = 8 and 12x - 10y = 16 has no solution. the system of linear equations 7x + 2y = 6 and 14x + 4y = 16 has an infinite number of solutions. the system of linear equations 8x - 3y = 10 and 16x - 6y = 22 has no solution. the system of linear equations 9x + 6y = 14 and 18x + 12y = 26 has an infinite number of solutions.

How many and of which kind of roots does the equation f(x)=2x^4−9x^3+17x^2−16x+6 have?
