Answer:
It takes 2.4 hours to travel 480 miles.
Step-by-step explanation:
From the graph race car is moving at 100 miles in 0.5 hours. So, in 1 hour, car could travel 2*100 =200 miles per hour.
So, we can set up equation as
y= 200x.
Plug in y as 480 then solve for x.
480 =200x
Divide both sides by 200
2.4=x
So, it would take 2.4 hours.
Answer:
Step-by-step explanation:
First, find the slope of the given line by finding two points. (0, 3) and (1, 1)
Use the equation for slope rise/run to find the slope.
From the left point to the right point, it goes down 2 units and to the right by 1 unit
-2/1 = -2 = slope
We already know the y-intercept which is y = 3, when x=0 and when the line crosses the y-axis
y=-2x+3 is the equation of the line.
Perpendicular line's slope is the opposite reciprocal of the original line's slope. Opposite reciprocal of -2 would be 1/2
y = 1/2(x)
y=1/2x -5/2
Answer:
Step-by-step explanation:
Putting value of n = - 8 in the equation
F(n) = 2n− 5
F(-8) = 2(-8) - 5
= - 16 - 5 = - 21
