In second equation add 0.74 and y to both sides: 3.25x+0.74=y;
Substitute y in the first equation: -4.5x-2(3.25x+0.74)=-12.5;
Distribute multiplication over addition:
-4.5x-6.50x -1.48=-12.5;
Combine like terms and add 1.48 to both sides:
-11x= -12.5+1.48;
-11x= 11.02 divide both sides by -11;
X= -11.02/11= -1.00(18)
Y= 3.25• -1.00(18)+.74= -2.515(90)
Answer:
2035.75 cm/min
Step-by-step explanation:
-Since the two gears are connected by the same chain, they have the same linear velocity.
-Linear velocity is distance covered over time:

Hence, the linear velocity of both gears is 2035.75 cm/min
Step-by-step explanation:
there are more than one way it depends what the question gives you but the easiest way is from the graph by the graph you can calculate them both for the domain you can determine it through the graph or the function by find when the function is undefined but for the range you should have the graph or drow it by the function to calculate it
