I think your answer is B but I’m not sure sorry I hope I helped
The correct answer would be 6.
To figure this out, you take the square root of 36 since area of a square is side x side.
f(x) = -2x + 1 works with (-1, 3)
f(x) = -2x^2 - 4x + 1 works with (0,1)
f(x) = 2sqrt(x + 2) + 1 works with (2, 5)
In order to find each of these, you need to try the ordered pairs in the equation and look for them to come out as true statements. Below is the work of trying each one.
(-1, 3)
f(x) = -2x + 1
3 = -2(-1) + 1
3 = 2 + 1
3 = 3 (TRUE)
(0,1)
f(x) = -2x^2 - 4x + 1
1 = -2(0)^2 - 4(0) + 1
1 = 0 + 0 + 1
1 = 1 (TRUE)
(2, 5)
f(x) = 2sqrt(x + 2) + 1
5 = 2sqrt(2 + 2) + 1
5 = 2sqrt(4) + 1
5 = 2(2) + 1
5 = 4 + 1
5 = 5 (TRUE)
Answer:
y = -108/5
Step-by-step explanation:
An inverse variation is xy = k where k is a constant
xy =k
6*-18 = k
-108 = k
xy = -108
Let x = 5
5y = -108
Divide by 5
y = -108/5
