Answer:
Quadratic, Linear, Exponential.
Step-by-step explanation:
You can find the average difference between rows. For example, in the first one, between the ys, it changes by 1, then 3, then 5, then 7. If you look at the changes between these you get 2 each time. Because you had to look at the differences twice, its quadratic. It's linear if you had to look at it once. Exponential you can just see if you can multiply the same constant between each row.
<span>r = 3 × v + 13
</span><span>r = 3 × 9 + 13
</span><span>r = 27 + 13
v = 40</span>
So cost=50+75t
so 200=50+75t
subtract 50 from both sides
150=75t
divide both sides by 75
2=t
$200=2 hours
50+75t=cost
300=50+75t
subtract 50 from both sides
250=75t
divide both sides by 75
10/3=t=200 mins=3hours 20 mins=$300
54.60/3.90=14
