Step-by-step explanation:
To graph, use y=mx+b as a guide where m is the slope and b is the y-intercept.
y=-3x-4
Start at -4 on the y-axis. Plot a point. This is the y-intercept b. From this point count down 3 units and 1 unit to the right. Plot this point and connect.
y=3/4x +2
Start at 2 on the y-axis. Plot a point. This is the y-intercept b. From this point count up 3 units and 4 units to the right. Plot this point and connect.
Alright, so he went the same distance there and back, but at different speeds
hmm
d=st
d/s=t
total time is 9.5hr
alright
so distance there=distance back we will call both of them d
so
speed there is 10
speed back is 9
total time is 9.5
so
d/sthere+d/sback=totaltime
d/10+d/9=9.5
times both sides by 90
9d+10d=855
19d=855
divide both sides by 19
d=45
he can ride 45mi away
Answer:
7/22
Step-by-step explanation:
Area = 400/200 × 400/200 ×1/4 × 7/22 = 7/22
You would have to put 21.3 on top and 1.9 under it. then you would have to borrow the number. the answer would be 19.4
