t‐shirts cost $12.99 each for the first 5 shirts purchased. each additional t‐shirt costs $4.99 each. describe and correct the error in the graph below that represents the relationship between total cost and number of shirts purchased.

  q

step-by-step explanation:

each line from a vertex to the midpoint of the opposite side is called a median. the point where the medians intersect, point q, is the centroid.

the centroid of δabc is point q.

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.

3

step-by-step explanation:

because where the point where the 2 lines intersect is (3,-1) the x value is 3
