An electrical shop reduces display goods by 10% a display TV is sold for $360. What is the usual price of the same TV

Usual price of the TV = $ 400

Step-by-step explanation:

Let x  be the usual price of the TV

Reduction = 10%

(100 -10)% of x = $360

90% of x = 360

x = 4 * 100

x=$ 400

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.
