Alejandro has a computer support business. He establishes that the cost to run his business can be represented by , where x is the number of customers. He also estimates that his income can be represented by . How many customers will Alejandro need in order to break even? (a) Assign Labels

(b) Write an Algebraic Model

(c) Solve the System of Equations

(d) How many customers will Alejandro need in order to break even?

(e) What will his profit be if he has 60 customers?

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)

center (1,3) with radius 6

step-by-step explanation:

we must complete the square to find the center and radius of the circle.

first make sure the x and y squared terms have 1 as their coefficients. we also make sure x and y terms together.

we now create space between the x and y terms with parenthesis.

we complete the square by taking the middle terms -2x and the -6y - divide each and square them.

we add the squares to both sides.

simplify.

and write the quadratics in factored form.

the center is (h,k) or (1,3). the radius is the square root of 36 which is 6.
