I think it's the first choice. T and F = F. hope this helps :D
Hi!
The answer is B. Linear function.
A linear function is when the change in <em>y </em>and <em>x</em><em> </em>is constant. For example, let's make some <em>x</em> and <em>y</em> values.
x 1, 2, 3, 4, 5
y 2, 4, 6, 8, 10
When <em>x</em> increases by 1, <em>y</em> increases by 2. The change in <em>x</em> and <em>y </em>is constant, therefore, that is a linear function.
x 6, 9, 13, 26
y 3, 5, 10, 11
There is no pattern in those numbers, therefore this is not a linear function.
Hope this helps! :)

Answer:
I honestly think it is C.
Step-by-step explanation:
Since "4 bottles of shampoo for every 3 bottles of conditioner" is (4,3), I think the 16 is (16,12) on the graph. It might be worng, might be right. Just go for C.
Answer:
4 mph
Step-by-step explanation:
Travel time is proportional to distance and inversely proportional to speed. If c represents the speed of the current in miles per hour, an equation for the total trip time is ...
825/(29 -c) +825/(29 +c) = 58 . . . . . . hours travel time
825(29 +c) +825(29 -c) = 58(29 -c)(29 +c)
58c² -928 = 0 . . . . . . . rearrange to standard form
58(c -4)(c +4) = 0 . . . . factor
Values of c that satisfy this equation are 4 and -4. For the purpose here, we'll choose the positive solution.
The speed of the current is 4 miles per hour.
