Answer:
45
Step-by-step explanation:
We can first expand the expression:
n(n+p) - n
= n^2 + np + n
Then, we can plug in values of n and p into the expression:
n^2 + np + n = (5)^2 + (5)(3) + 5 = 25 + 15 + 5 = 45
If (7, -4) is on the graph of F(x), then (-4, 7) is on the graph of F⁻¹(x).
I think that the value of f-1(3) is 2
And then i think that the value of f-1(8) is 5
I am not 100% sure but i think that thats it lol
Janek miałby 12 samochodów, Bolek miałby 16, a Antek miałby 6 samochodów. Nie jestem do końca pewien, czy to prawda, ponieważ mówimy różnymi językami, ale mam nadzieję, że to pomoże!
Let x be the number RIGHT of questions
Amount scored for the x RIGHT questions = 12x
The end result is: 12x -7 = 209
12x = 216 and x = 216/12, x = 18.
So she had 18 correct answers (and 7 wrong)
