Answer:
y = 2x -4
Step-by-step explanation:
-10x + 5y = -20
+10x +10x
5y = 10x -20
5 5 5
y = 2x - 4
Answer:
2 miles
Step-by-step explanation:
60 min = 1 hour
24 min = x
x = 2/5 hour
1 hour = 5 miles
2/5 hour = y
y = 2 miles
Marginal profit, P(x) = R(x) - C(x)
P(x) = x³ - 5x² + 7x + 10
x³ - 5x² + 7x + 10 = 0
If you solve it, you get x = -0.839 where P(x) is zero
28 degrees is the answer , 76+76= 152, 180-152+ 28
Answer:
53.2 mph
Step-by-step explanation:
Mara's family travels 239.4 miles between the hours of 9:10 a.m. to 1:40 p.m.
1:40 p.m. is 13:40.
Thus, they traveled for
13 hours 40 minutes - 9 hours 10 minutes = 4 hours 30 minutes
that is hours.
Use formula:
where
D = distance
r = rate
t = time.
In your case,
D = 239.4 miles
t = 4.5 hours
