Answer:
g(x) - f(x) = -14x - 3
Step-by-step explanation:
We need to subtract the function f(x) = 9x + 4 from the function g(x) = -5 + 1. Rewriting these two functions in columns, we get
g(x)= -5x+1
- f(x) = -(9x+4) Note: Use parentheses as shown here.
--------------------
g(x) - f(x) = -14x - 3
Clearly, y = 4x.

The cost is proportional to the number of bags, so you really only need one point to determine the constant of proportionality. The point (1, 4) will tell you directly what the cost of 1 bag of peanuts is.
The length of the pool is 1500 cm. Hope it help!
Answer:
The value of x is inversely proportional to the difference of <em>a</em> and <em>b</em>.
Step-by-step explanation:
The given expression is
We factor the left hand side to get:
We divide both sides by: a-b
Observe that the difference of a and b is in the denominator.
The whole is of the form:
The value of x is inversely proportional to the difference of <em>a</em> and <em>b</em>.
