Solve the given matrix equation for X. Simplify your answers as much as possible. (In the words of Albert Einstein, "Everything should be made as simple as possible, but not simpler") Assume that all matrices are invertible. a. XA-1 = A3b. AXB = (BA)2 c.(A-1 X)-1 = (AB-1)-1(AB2) d. ABXA-1 B-1 =1 + A

Find the solution(s) to x^2-14+49=0

Can someone me with this? i’m not sure what to put for my equations.

Paula makes stained-glass windows and sells them to boutique stores. if her costs total $12,000 per year plus $4 per window for the frame. how many windows must she produce to earn a profit of at least $48,000 in one year if she sells the windows for $28 each? 1. define a variable for the situation. 2. write an inequality that represents her profit. note: revenue is money coming in. cost is money going out. profit is the difference between the revenue and the cost. in other words: revenue - costs profit 3.using words, describe how many windows she must sell to have a profit of at least $48,000.
