Why do you think the following statements are true or false? Demonstrate whether each of them is true or false for polynomials over a field:
1. The product of monic polynomials is monic 2. The product of polynomials of degrees m and n has degree m
1.) Solve the system by substitution x+y=12 y=12 Since Y = 12, we can substitute for y in the first equation as follows: X + 12 = 12 X=0 X = 0, and y = 12 (0,12) 2.) Solve the system by substitution 3x-y =-7 (Equation 1) x+y=-9 (Equation 2) From Equa
What would the equation be of line L, if L has an intercept (0,2) and is perpendicular to the line with equation 2x-3y=6 Perpendicular lines have slopes that are negative reciprocals of each other. For example, if an equation has a slope of 2, the eq
A plane flies 480 miles with the wind and 320 miles against the wind in the same length of time. If the speed of the wind is 28mph, what is the speed of the plane in still air? Let the speed of the plane in still air be x The speed of the plane with
A,B, and C can finish a job in 6 days. If B and C work together, the job will take 9 days; if A and C work together, the job will take 8 days. In how many days can each man working alone do the job? A. A in 9 days, B in 1 day, and C in 8 days B. A in
Which set of equations represents the given equation after they have been cleared of fractions.? 2x+16/11+y-1/3=3 3x+3/4-2y-3/5=2 A. 2x-11y=114 3x+2y=80 B. 2x+y=84 3x-2y=34 C. 6x+11y=62 15x-8y=13 D. 6x+11y=99 15+8y=40 To answer this question, find th
After a new firm starts in business, it finds that its rate of profit (in hundreds of dollars) after t years of operation is given by P'(t)=3t^2+8t+5 Find the profit in year 7 of the operation.

= 3(49) + 56 + 5 = 147 + 56 + 5 = $
I am working on the systems of inequalities and my problem is Y>50 and X>100. I have to graph the inequalities to find the solution set, label the intersection, and then select the intersection region. I had to use the two point graphing system. I ha
