Hey there! :D
If you divide both sides by 9:
9/9=1 36/9=4
1:4 is equivalent.
I hope this helps!

Here is the work! The zeros of the graph are at -1 and 3
6/48 simplified would be 1/8.
Answer:
319 seconds
Step-by-step explanation:
The distance 12.42 miles is equivalent to
12.42*5280=65577.6 ft
When slope is 6.4%,
Therefore,
Also
Making t the subject of the formula by solving quadratic equation
t=318.4791278210496
Therefore, time is 319 seconds
We could put the domain into the x values to get the y values (range).
y = 3(-3) - 4
y = -9 - 4
y = -13
y = 3(-1) - 4
y = -3 - 4
y = -7
y = 3(4) - 4
y = 12 - 4
y = 8
