Answer:
65 miles every 1 hour
Step-by-step explanation:
Unit rate is found once one of the units is 1. In this case we need to reduce the ratio so that it is 1 hour and we get a unit rate. We can do this by dividing both sided by 2 so that the hours are reduced to 1.
130=2
130/2=65 2/2=1
65=1
65 miles every hour
It would take 20 hours since 8,000 times 5 is 40,000 so 4 times 5 is 20.
Logic.
Answer:
B
Step-by-step explanation:
y=n(x+5)(x-3)
or y=n(x²-3x+5x-15)
or y=n(x²+2x-15)
=n(x²+2x+1-1-15)
=n(x+1)²-16n
y -coordinate of vertex=-16n
Answer:
-1
Step-by-step explanation:
The given equation has a y-intercept of 8, so goes through the point (0, 8).
If the line also goes through the point (2, 6) it has a slope of ...
(y2 -y1)/(x2 -x1) = (6 -8)/(2 -0) = -2/2 = -1
The slope of the line is -1.
