Step-by-step explanation:
Hello!
Recall that the equation of an exponential graph is:
We can see from the graph there is a y-intercept at y = 5. Plugging in 0 for x results in:
Solve for b by plugging in another point on the graph:
Write the final equation:
9514 1404 393
Answer:
- 3 big bucks
- 6 little bucks
- 17 does
Step-by-step explanation:
Let B, L, D represent the numbers of big bucks, little bucks, and does, respectively.
B + L + D = 26 . . . . . . total bagged
D = 5 + 2L . . . . . . . . . 5 more does than twice the number of little bucks
B = L/2 . . . . . . . . . . . . half as many big bucks as little bucks
__
We can substitute for B and D in the first equation:
L/2 + L + (5 +2L) = 26
7/2L = 21 . . . . . . . . . . . . . subtract 5, collect terms
L = 6 . . . . . . . . . . . . . . . . . multiply by 2/7
D = 5 + 2·6 = 17
B = 6/2 = 3
The party bagged 3 big bucks, 6 little bucks and 17 does.
Answer:
23.167168n−9
simplify
n-5+(3n/n(2.718282^2))(n)-4=23.167168n2−9n=23.167168n−9
