Let us assume that 4 - 5h = 0
we need to the value of h.
4 - 5h = 0
-5h = -4
-5h/-5 = -4/-5
h = 4/5
To check: substitute h by its value.
4 - 5h = 0
4 - 5(4/5) = 0
4 - 20/5 = 0
4 - 4 = 0
0 = 0
The answer would be <span>99.99999989.</span>
You could try searching it up I’m sure it will pop up !
There is 3600 seconds per hour.
Multiply the speed per second by 3600 to get the speed in miles per hour then convert to kilometer/hour.
4.9 * 3600 = 17,640 miles per hour
17,640 x 1.6 = 28,224 kilometers per hour
To write it in function notation you'll convert it into a function, substituting y by f(x):
y = 3x - 8 = f(x) = 3x - 8
