Inside the square root shouldn't be negative, so x must be negative in order to form positive number inside the root.
if x = 0, y = 0
if y = -1, y = -1
if y = -4, y = -2
if y = -9, y = -3
the points lie on the graph (0,0), (-1,-1), (-4,-2), (-9,-3)

bookshelf is 45 inches
each book is 1 1/2 inches
45 / 1 1/2 = 30
30 books can fit on the shelf
Y = 2x/x-7
x = 2y/y-7
xy - 7x = 2y
-7x = 2y - xy
-7x = y(2-x)
y = -7x / 2-x
y = 7x / x-2
f-¹(x) = 7x / x-2
Answer:
Chris gets £3000
Step-by-step explanation:
A : B : C
1 : 3 : 4 = 8 (add all the parts together)
£6000 ÷ 8 = 750
so the multiplier is x 750
1 : 3 : 4
↩ x 750
750 : 2250 : 3000
Chris gets £3000
