This would be 45.9
Get a calculator or try long division :-)

Let
, so that differentiating both sides wrt
gives

If
and
, the above reduces to

This is the slope of the tangent line, which has equation

I have the same question and I have no idea sorry
Answer:
b) 2/6
Step-by-step explanation:
0, 1/6, 2/6, 3/6, 4/6, 5/6, 1
Hope this helps!
Slope intercept form is y = mx + b
7 tickets for $5 means that 1 ticket costs 5/7 dollars
So for part a, the slope intercept form would be:

where x is the number of tickets, and y is the price.
For part b)
The slope intercept form is:

where x is the number of all you can ride wristbands you buy, and y is the total price.
