7-4=3
10-7=3
13-10=3
we can see that this is an arithmetic sequence with a difference of 3
the nth term=the first term +(n-1) times the difference
so a(n)=4+3(n-1)
I believe A Formula
Sorry if im wrong...
R = Rate of gasoline by automobile = 35 mi/gal
it is given that , 1 kilometer = 0.6214 miles
and 1 gallon = 3.78 liter
so
R = 35 (miles/gallon) (1 kilometer/0.6214 miles) (1 gallon/3.78 liter)
R = (35) (1/0.6214) (1/3.78) (miles x 1 kilometer/1 miles) (1 gallon/(1 gallon x 1 liter))
R = 14.9 kilometer/liter
A= a+b/2 *h
6.5 = a+4/2 * 2
6.5/2 = a+4/2 *2/2
3.25 = a+4/2
3.25*2= a+4/2*2
6.5 = a+4
6.5-4 = a+4-4
2.5 = a
The missing measure is 2.5
Check
6.5= 2.5+4/2 *2
6.5= 2.5+2*2
6.5=2.5 + 4
6.5=6.5
Answer:
a) Yes, i think it does represent a proportional relationship because the prices all go up by 12$.
b) The constant of proportionality is 12.
c) The equation would be 12(t) t= tickets idrk how else to put the equation feel free to correct me if im wrong.
D) the graph would look like : on the x axis would go up by 1,2,3,4,5,6 and so on, and on the y axis, count by 12's. (ex. 12,24,36,48)
E) The cost of 7 tickets would be 84$
Step-by-step explanation:
I explained above.
