The answer is 4.5 hours.
120 miles/2 hours = 60 mph
270-120 = 150 miles
150 miles/60 mph = 2.5 hrs
2 hrs+2.5 hrs = 4.5 hours for the whole trip
Answer:
The end behaviour of all the functions is same ie they all tend to zero.
Step-by-step explanation:
In every option the function f(x)is a linear function which tends to infinity at the end(as x tends to infinity).Now the function g(x)in every option is just the reciprocal of f(x).As we all know
∞
then
Use slope formula to find slope
<span><span><span>−9−5</span><span>−/12−8</span></span>=<span><span>−14/</span><span>−20</span></span>=<span>7/10</span></span>
7/10 = m = slope
y= mx + b
y= (7/10)x + b
(8,5)
(5) = (7/10)(8) + b
b = -3/5
So....
<span>y=(<span>7/10)</span>x −<span>35
</span></span>
multiply by 10
<span>10y=7x−6</span><span>
--> -7x + 10y = -6
--> 7x - 10y = 6
So, if 7x - 10y = 3 a good model?</span>
The two expressions could be :
2 - 1/2m
2 - m / 2
Answer:
450 minutes
Step-by-step explanation:
1 hour and a half = 90 minutes in one day
90 (minutes) × 5 (days) = 450 minutes
