Work out the percentage change when a price of £10 is decreased to £8

20%

Step-by-step explanation:

Calculate percentage change as follows

percent change = × 100%

decrease = £10 - £8 = £2

percent change = × 100% = = 20%

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.
