76 ÷4=19
76/4+10=x
19+10=x
29=x
There is 29 questions on the test, and he got 19 correct. (65.5%)
good luck
Answer:
39430 each
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.
He will have 22,900 by December.
Answer:
3/10, 0.3, 3:10
Step-by-step explanation:
It is 3/10, 0,3, 3:10 probability because if you have 10 slices, and 3 of them are blue, then you only have 3 tenths probability of landing on it. So, it is either, 3/10, 0.3, or 3:10. (Depending on how you are learning it).
