No.of stamps Billy had = 55
Number of stamps Billy's older brother had = 73
So total number of stamps two brother have together = 73 + 55
= 128
Answer:
x = 2
Step-by-step explanation:
(x + 50)/2 = 13x, first multiply both sides by 2
x + 50 = 26x, next subtract x from both sides
50 = 25x, finally divide both sides by 25
2 = x
Given an exponential function, say f(x), such that f(0) = 1 and f(1) = 2 and a quadratic finction, say g(x), such that g(0) = 0 and g(1) = 1.
The rate of change of a function f(x) over an interval

is given by

Thus, the rate of change (growth rate) of the exponential function, f(x) over the interval

is given by

Similarly, the rate of change (growth rate) of the quadratic function, g(x) over the interval

is given by

Therefore, the exponential grows at the same rate as the quadratic in the interval <span>

Answer:
(a)
(b)
Step-by-step explanation:
Alphaville's Budget Surplus Model is 
Betaville's Budget Surplus Model is 
We want to determine the expression that shows how much greater Alphaville’s annual budget surplus is than Betaville’s for a particular amount of tax revenue.
- To do this, we subtract Betaville's Model from Alphaville's model.

Opening the brackets

Collect like terms and simplify

The expression that shows how much greater Alphaville's Budget is:

(b) If the tax revenue that year in each town is $75,000
We want to evaluate the expression derived above when the tax revenue that year in each town is $75,000 i.e.at x=75000
