Answer:
$68.80
Step-by-step explanation:
First you need to find 60% of 48 which is 28.8. Then you add the 28.8 and 48 to get a total of $68.80.

Part A)The given equation is:
![25 x^{2} +10x+1=0](https://tex.z-dn.net/?f=25%20x%5E%7B2%7D%20%2B10x%2B1%3D0)
The radicand or discriminant(d) of the equation will be:
![d=(10)^{2}-4(25)(1) \\ \\ d=100-100 \\ \\ d=0](https://tex.z-dn.net/?f=d%3D%2810%29%5E%7B2%7D-4%2825%29%281%29%20%5C%5C%20%20%5C%5C%20%0Ad%3D100-100%20%5C%5C%20%20%5C%5C%20%0Ad%3D0%20)
Since the discriminant is equal to 0, the given quadratic equation has only 1 root. In other words we can say the the given equation is a perfect square.
Part B)The given equation is:
![4 x^{2} -4x+1=0](https://tex.z-dn.net/?f=4%20x%5E%7B2%7D%20-4x%2B1%3D0)
We can solve this expression by factorization. Factors of middle term are to be made in such a way that their product equals the product of first and third term and sum is equal to the middle term i.e. product should be 4x² and sum should be -4x.
So the two such terms are -2x and -2x. Using the factors and simplifying the equation by taking common we get:

Answer:
g^-1(x) = (x - 5)/-6
Step-by-step explanation:
g^-1(x) refers to an inverse function. To find any inverse function, we must replace g(x) with x and x with g(x). We can then solve for the new g(x) and that would be the composite function.
g(x) = -6x + 5 ------> Swap x and g(x)
x = -6g(x) + 5 -----> Subtract 5 from both sides
x - 5 = -6g(x) ------> Divide by -6
(x - 5)/-6 = g(x)
