To answer this item, we let x represent the original price of the object or the fridge before it happened.
The representation would lead us to conclusion that the total amount to be paid is equal to,
1.20x = £480
The value of x from the equation,
x = 400
The answer is <span>£</span>400

Square the binomial :)
Step-by-step explanation:
Hello!
173 + 32 = 205
5 * 205 = 1025
Answer:
y = -16
Step-by-step explanation:
f(x)=3/4x+12 (replace f(x) with y)
y =3/4x+12 (rearrange to express x in terms of y)
y - 12=3/4 x
3/4 x = y - 12
3x = 4(y - 12)
x = (4/3)(y - 12)
x = (4/3)y - (4/3)(12)
x = (4/3)y - 16
(y) = (4/3)y - 16
(x) = (4/3)x - 16
comparing to general form
y = mx + b where b is the y-intercept
b = -16
Hence the y-intercept is y = -16
