5.25% of $15.49 is 81¢ approximately. Therefore the total cost is $16.30.
Step-by-step explanation:
Using the Intermediate Value Theorem, the following is applied:
"If f(x) is a continuous on interval [a,b] and we have two points f(a) and f(b) then there must be some value c such that f(a)<f(c)<f(b).
So here there must be a c such that
![f(0) < f(c) < f(1)](https://tex.z-dn.net/?f=f%280%29%20%3C%20f%28c%29%20%3C%20f%281%29)
Note: F(c)=0, the questions that the function have a solution between 0 and 1, so that means we must have some value, c such that f(c)=0 that exists
Next, plug in the x values into the function
![f(0) = - 4](https://tex.z-dn.net/?f=f%280%29%20%20%3D%20%20-%204)
![f(1) = {1}^{3} + 7(1) - 4 = 4](https://tex.z-dn.net/?f=f%281%29%20%3D%20%20%7B1%7D%5E%7B3%7D%20%20%2B%207%281%29%20-%204%20%3D%204)
Since cubic functions are continuous and -4<0<4, then there is a solution c that lies between f(0) and f(1)

Step-by-step explanation:
Answer: x= -2
Step-by-step explanation: use pemdas
10x + 8 = 3(x - 2) distribuite parenthesis
10x + 8 = 3x - 6
10x + 8 = 3x - 6 add like terms
7x +8= -6 add like terms
7x= -14 divide to get x alone
x= -2
