Answer:
73 mph during the second hour!
Step-by-step explanation:
Hour 1=54 mph
Hour 2=? mph
Hour 3=82 mph
Total=209 mph
this means that 209=82+54+?
Simplify it and you will get 73
73 mph
Answer:
12
Step-by-step explanation:
Direct Variation. I think it's gonna be like this.
SInce Z is not inversely to y , its varies directly to both.
Then it's,
Z=kxy, where k is constant.
subst. Z=6,x=2 and y=6.
6=k×2×6
6=k×12=12k
6=12k=½
the formula connecting them is
Z=½xy
Z=½×3×8
Z= 1×3×8÷2
Z=24÷2
Z=12.
That's my solution.
Answer:
y = -1/3 x + 2
Step-by-step explanation:
slope is change in y over the change in x
5-2/-6-0 = 3/-6 = -1/3
y - 2 = -1/3 (x -0)
y = - 1/3x + 2
