The rate is 0.30 km/min. The rate in linear functions, which must be assumed with only two given points can be traced to calculating the slope (m) of the line or rate.
m= (y2-y1) / (x2-x1)
with our two given points (x,y) we fill out the equation as:
M= (12 - 0) / (40 - 0) or M = 12/40 = 0.3
keeping our units intact 12 km / 40 min so the answer is 0.3 km/min
12x + 20 = 4(3x + 5)
gcf = 4
Hello!
375/1000 = 0.375 as a fraction
This can be simplified to 3/8
The answer is 3/8
Hope this helps!
