Answer:
f(t) = 160t,
d = f(t)
The function that relates the distance traveled d to the time t is:
f(t) = 160t, where d = f(t)
Step-by-step explanation:
If the train travels 480 kilometers in 3 hours, then it will travel 160 kilometers in one hour:
d = 160t
Now we replace d by f(t) because d = f(t):
f(t) = 160t
for any given value of t, d will be equal to t multiplied 160 times
Bring all the terms to one side.
x^2+5x–5x –43 –6 = 0
x^2–49=0
x^2 = 49
x = +- 7

Answer:
MO = 17
Step-by-step explanation:
First, you need to define what if the unknown x.
segment MN and NO are equal to MO.
thus, your equation for the combination is x +8
Now set the values equal to each other
x + 8 = 3x - 10 (subtract x from both sides)
8 = 2x - 10 ( get your x value alone, add 10 to both sides)
18 = 2x (simplfy)
x = 9
Now plug x value into MO
3 (9) - 10 = 17
Check with opposing equation:
9 + 8 = 17 √
