Tickets for a school play cost $6 each. Brandy sold 8 tickets to her father, then sold another x tickets to her aunt. Brandy ended up collecting $66. Write an equation that can be used to find x, number of tickets sold to her aunt.

(x+ ) =

just take the area of the square and then the area of the circle then subtract the circle area from the squares area

step-by-step explanation:

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
