Answer:
a:multiply the unit rate by 5 hours and see if it equals the total distance.
Step-by-step explanation:
First, change the division sign to multiplication, and flip the second fraction
(1/4)/(9/10) = 1/4 x 10/9
1/4 x 10/9 = 10/36
10/36 is your answer, and there is not enough in the numerator to change into an mixed fraction.
hope this helps
Answer:
The cost of traveling 25km would be $3000.
You can travel 35 km for $4200.
Step-by-step explanation:
Consider the provided information.
For 30km cost $3,600.
30 km = $3600
Divide both sides by 30.

....(1)
The cost of 1 km is $120.
Part (A) what would be the cost of traveling 25km
Multiply both the sides of equation 1 by 25.
25 km = 3000
Hence, the cost of traveling 25km would be $3000.
Part(B) How far could you travel for $4,200?
Divide 4200 by 120.

Hence, you can travel 35 km for $4200.
Basically see where it intersectst the y axis
that is where x=0
so set x=0 and solve
3(0)^2-1/2(0)+4+1
4+1
5
the y intercept is at y=5, so yo uknow that (0,5) is on the graph
