Vanessa gives a quarter of her share to Jack.
How much money does Jack receive?

£3.66

Step-by-step explanation:

17+23=40

40=16 what about 17

16×17=272÷40=£6.8

16-6.8=£9.2

20% of £6.8 = £1.36

1/4 of £9.2 = £2.3

1.36+2.3=£3.66

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.
