Answer:
there the same ratio because there both offering the same ratio of of there number
3x10=30 ratio : 10
2x10=20 ratio: 10
Step-by-step explanation:
Choices A and B have typos in them, so its not clear what you're trying to say for those parts. However, the domain of 
is 
meaning that x can be 0 or larger. In other words, we can't have x be negative. Similarly, y is the same story because has the inverse 
, but only when , so therefore 
as well. In short you can say both x and y are nonnegative.
To summarize so far, the domain is and the range is
Since x = 0 and y = 0 are the smallest x and y values possible, this means (x,y) = (0,0) is the left-most point or where the graph starts. This is the origin. Choice C is a true statement.
Choice D on the other hand is <u>not</u> a true statement. Graph out and you'll see that a straight line does not form, but instead a nonlinear curve that grows forever. That growth gradually diminishes as x gets larger. Algebraically you can pick three points from the function and show that the slopes are different. Say the three points are P, Q and R. If you can show that slope of PQ does not equal slope of QR, then the function is not linear.
The top-left one because 3ba is the same as 3ab
640×3= 1,920 Then you don't need to estimate it since it's estimated.
hope this helps :-)<span />
Answer:
-$11.34
Step-by-step explanation:
Cost of 6 tickets = $68.04
Aylor's account balance showed a change of −$68.04
Cost of 1 tickets = cost of 6 tickets / 6
= $68.04 / 6
= $11.34
change to Taylor's account balance had he only bought 1 ticket to the movie will be -$11.34
