Answer:
y=55x
given y=385
x=gallons of gas = 385/55 = 7 gallons
inverse function
y=55x
change x to y and y to x
x=55y
y=x/55
inverse function is x/55
Step-by-step explanation:
The rate of change would be 7. you would plot your first point on the graph at (-2,0) and the next one would be up 7 and over 1 for your next plot point.
Answer:
The first one is 75 and the second one is 81
Step-by-step explanation:
put 187.5 into calculator then divide it by the bottom number/denominator in this case 2.5 and then you get 75
put 303.75 into calculator then divide it by the denominator or 3.75 and you get an answer of 81
so 81 miles per hour
I really hope this helps!
