Answer:
\/
Step-by-step explanation:
Let x = number of half-gallons the store bought
(x-15) is the number of half-gallons the store sold
Profit = Income - Cost
$65.72 = (x-15)*3.96 - (x)2.60
65.72= 3.96x - 59.40 - 2.60x [distribute]
125.12 = 1.36x [collect terms]
92 = x
Step-by-step explanation:
what is the question you are just showing us the lesson and modle
Answer:
0.111111...
Step-by-step explanation:
Hi,
this function is stating that for any x the f is 9(3)^x.
SO if x was -4 it would be 9(3)^-4
Following order of operations we calculate the exponent first.
the answer is 0.1111111...
could you explain a bit more?
Answer:
Option D is correct
The exponential function is:
Explanation:
An exponential function is in the general form is:
. ......[1]
Given the points (1,12) and (2, 36).
For the point (1,12),
Plug in x = 1 and y =12 in [1]; we get
or
12 =ab ......[2]
Now, for the point (2, 36);
Plug in x= 2 and y =36 in [1];
......[3]
Divide equation [3] by equation [2], we have
Simplify:
Substitute the value of b in equation [2], to solve for a;
Divide both side by 3 we get;
simplify:
Then, put these a and b values in [1]; we get
The exponential function as:
