Adata set consists of the following data points: (2, 4), (4, 7), (5, 12)the line of best fit has the equation y = 2.5x – 1.5. what does this equation predict for a value of x = 3?

C) 6

Step-by-step explanation:

We will substitute 3 in place of x:

y = 2.5(3) - 1.5

y = 7.5 - 1.5

y = 6

trapezoid

step-by-step explanation:

first i plotted all my points on a grid graph

i made sure all of them were in the correct quadrant

then i saw it was a trapezoid or a quadrilateral

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.
