A plumber has a call out fee of $33 and then charges $21 per hour.
Write an equation to determine the total cost of a
house call after x, hours.

y=21x+33

Step-by-step explanation:

Your flat fee is added at the end becuase you are only charged once, but hourly it is 21 dollars, when you plug in your hours as x you will get the total cost being y

answer: (-8,4) are the coordinates of a

step-by-step explanation:

let the side of square abcd is x .

thus the area of square abcd is .

now, by the diagram area of triangle ead= 1/2 × ea × ad = 1/2 × ea × x

( because ad is the side of square)

and, according to the question,

the areas of square abcd and right ead are equal.

⇒

⇒ea=2x

thus, ea: ab=2: 1

therefore, point a divides line segment eb into the ratio 2: 1.

⇒ by sectional formula coordinates of a are,

=

=

=(-8, 4)

thus the coordinates of a are (-8,4)

v=1788.75
