A) y = 2x – 7 and f(x) = 7 – 2xIncorrect. These equations look similar but are not the same. The first has a slope of 2 and a y-intercept of −7. The second function has a slope of −2 and a y-intercept of 7. It slopes in the opposite direction. They do not produce the same graph, so they are not the same function. The correct answer is f(x) = 3x2 + 5 and y = 3x2 + 5. B) 3x = y – 2 and f(x) = 3x – 2Incorrect. These equations represent two different functions. If you rewrite the first equation in terms of y, you’ll find the equation of the function is y = 3x + 2. The correct answer is f(x) = 3x2 + 5 and y = 3x2 + 5. C) f(x) = 3x2 + 5 and y = 3x2 + 5Correct. The expressions that follow f(x) = and y = are the same, so these are two different ways to write the same function: f(x) = 3x2 + 5 and y = 3x2 + 5. D) None of the aboveIncorrect. Look at the expressions that follow f(x) = and y =. If the expressions are the same, then the equations represent the same exact function. The correct answer is f(x) = 3x2 + 5 and y = 3x2 + 5.

Answer:
5n + 75 n = 160
Step-by-step explanation:
this is because nickels are worth 5 cents and quarters are worth 25 cents and the total value is 1.60. but since we have three times as many quarters as nickels so we do 5n + 75n = 1.60. But the problem with this is the right side of the equation is in terms of dollars while the left side is in terms of cents, so we convert both sides to cents and we get 5n + 75n = 160.(we could make both sides in terms of dollars, but that wasn't one of the options) hope this helps:)
