80km x 3hr = 240km
45min = 3/4hr
80km/(3/4hr) = 20km
240km + 20km = 260km
Answer:
6 or -2
Step-by-step explanation:
|3t - 6| = 12
3t - 6 = 12

t = 6
3t - 6 = -12
3t = -6
t = -2

True
Answer:
D
Step-by-step explanation:
Between 1 and 3 months Jason's weight remained the same. During this time period the slope is 0, therefore, Jason lost no weight.
Standard form of an exponential function is y=ab^x
when x=0, y=3, 3=ab^0, so you can figure out that a=3
when x=-1, y=6, 6=3b^(-1), b^(-1)=2, b=1/2
so the equation is y=3(1/2)^x
