Opening night of the musical at Finns school sells 52 child tickets and 13 adult tickets for a total of $767. On the second night the musical sold 40 child tickets and 16 adult tickets for a total of $668. Find the cost of a child ticket

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.

b

inverse property is the answer

step-by-step explanation:

(5x-1)^2= (5x)^2-2(5x)×1+(1)^2=25x^2-10x+1
