Answer:
The number is 4.
Step-by-step explanation:
The difference of twice a number and 12 is 2x - 12.
Multiplying by 5 gives 5(2x - 12)
So 5(2x - 12) = -20
Solving for x
10x - 60 = -20
10x = -20 + 60 = 40
x = 40/10
x = 4.
It can go 630 miles because 4 needs to be multiplied by 3 to get 12 and so 210 needs to be multiplied by 3 to get the answer of how far on 12 gallons.
Answer:
what i got was 72 but your picture i am assuming is bigger for me than it is for you so i would say 51 miles
Hope it helps!

Step-by-step explanation:
6^2+8^2=100
sqrt of 100 = 10
If you start from the parent function 
, the only transformation performed is 
. In fact,
In general, a transformation like 
results in a horizontal stretch. If k>1, the function is compressed, if 0<k<1, the function is streched. If k is negative, the function is reflected around the y axis, and then you apply the logic just described.
So, in your case, k=9, which means that the graph is horizontally compressed by a factor 9.
