Use the slope formula which is;
slope= (y2 - y1)/ (x2 - x1)
slope= (9-1)/ (8-4)
Slope= (8)/(4)
Slope= 2
Horizontal means X axiz. so 6 units on the x axis. The points are always placed (x,y) which is A. (1,6) and (7,6)
Solution:
<u>Note that:</u>
<u>Using the clue above, let's solve each problem.</u>
- 10 mL = 10/1,000 L = 0.01 L
- 1.2 L = 1.2 x 1,000 mL = 1,200 mL
- 3,500 mL = 3,500/1,000 L = 3.5 L
- 4 L = 4 x 1,000 mL = 4,000 mL
- 230 mL = 230/1,000 L = 0.23 L
- 6.21 L = 6.21 x 1,000 mL = 6,210 mL
Hoped this helped!
Printer A prints for 10 minutes, so prints
... (30 pages/minute)×(10 minutes) = 300 pages
Printer B prints for 7 minutes, so prints
... (40 pages/minute)×(7 minutes) = 280 pages
At the end of 10 minutes, the two printers will have printed
... 300 pages + 280 pages = 580 pages
4 prints
12x = 2.5x + 38
at 4, these expressions are equal
