AB is the diameter of a circle. A is (1,3) and B is (7,-1).

(a) Find the equation of the circle. [3]

(b) The line y + 5x = 8 cuts the circle at A and again at a second point D. Calculate the coordinates of D. [4]

(c) Find the area of triangle ABD. [3]

answer: bea's uncle is 25 years old.

step-by-step explanation:

given the equation , we can say that the variable "x" represents the age of bea's uncle. then to find his age, we need to solve for "x":

we must add 15 to both sides of the equation:

now we need to divide both sides of the equation by 3:

therefore, we can conclude that bea's uncle is 25 years old.

“a term can be a signed number, a variable, or a constant multiplied by a + sign or j sign. in , the terms are 5x , 3y and 8. when a term is made up of a constant multiplied by a variable or variables, that constant is called a coefficient.” i hope this you.
