It takes a printer 2 1/2 min to print 24 black-and-white pages and 4 color pages. It takes the same printer 3 1/4 min to print 30 black-and-white pages and 6 color pages. Let b represent the time in minutes needed to print a black-and-white page and c represent the time in minutes needed to print a color page. The shown system represents the given problem: 24b + 4c = 2 1/2 30b + 6c = 3 1/4 FILL IN THE BLANKS... It takes the printer [BLANK] min to print a black–and–white page and [BLANK] min to print a color page.

5 pages/min*60 minutes=300 pages/hr

Step-by-step explanation:

. But as others noted, the way speed is claimed on inkjet 5 pages per minute is based on a “reference page“. Typically a very low coverage %. Coverage percentage refers to ratio of the ink covered surface of a sheet of paper divided by the whole area of the sheet. This could likely be less than 5 percent. This is important because inkjet print speed varies based on coverage percentage because the ink is sprayed on the page in passes that are as high as the print head itself (Typically around 1/2 to 1 inch high) The more coverage, the more passes are required back and forth as the paper moves past the print head. The more passes that are required the slower the paper moves through the printer. So you only get 5 pages per minute speed if your print is equal to or less than the % coverage the reference page has.

i think it's b

step-by-step explanation:

because the graph is 2 above (0,0)

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
