which function represents a reflection of f(x) = three-sevenths(2)x over the x-axis?

The given function is

f(x) = (3/7) 2^x

And it is to be reflected over the x-axis. This means that the function will have an opposite sign or -f(x). The resulting function after the reflections is

-f(x) = -(3/7) 2^x

I am pretty sure any way, good luck :)

Step-by-step explanation:

18.75x + 150 = 600; Clarissa’s sister will have $150 left to pay after 24 weeks.

Step-by-step explanation: The initial cost is 600 dollars and she has a payment plan of 18.75 dollars per week. This means she has 18.75 times x number of weeks to pay off the entire 600 dollars. Her payment plan can be expressed as follows;

18.75x = 600

However, she wants to make her weekly payments such that at a point she would be left with an outstanding payment of 150 dollars. In other words she wants to know when her weekly payment plus 150 would all be a total of 600. That is 18.75x plus 150 would be equal to 600. Our new equation based on this information is as follows;

18.75x + 150 = 600

18.75x = 600 - 150

18.75x = 450

Divide both sides of the equation by 18.75

x = 24

Hence after paying 18.75 dollars for 24 weeks (450 dollars) she would still have 150 dollars left unpaid.

Therefore the correct equation is;

18.75x + 150 = 600
